Colby McHenry 096114a776 feat(luau): add Luau language support
Index Luau (.luau), Roblox's typed superset of Lua. The luau extractor extends the Lua one and adds: `type`/`export type` aliases, typed function signatures, generics, and Roblox instance-path `require(script.Parent.X)` imports — alongside inherited functions, receiver-split methods, local variables, and call edges. Vendor the upstream ABI-14 tree-sitter-luau grammar.

The Roblox-path require handling lives in the shared Lua require helper (harmless for plain Lua). Addresses the Luau request in #232.

Colby McHenry 4ffe9229a7 feat(lua): add Lua language support
Index Lua (.lua): functions, methods (table `t.f`/`t:m` defs become methods with a `t::f` receiver), local variables, `require` imports, and call edges.

Vendor the upstream ABI-15 tree-sitter Lua grammar — the tree-sitter-wasms build is ABI 13 and corrupts the shared WASM heap under web-tree-sitter 0.25, dropping nested calls/imports after the first file in a project.

Harden the add-lang skill from this run: add check-grammar.mjs (flags ABI/heap corruption up front), document the DEFAULT_CONFIG.include edit and grammar health-check in SKILL.md, and add Lua repos to the eval corpus.

Colby McHenry 2fc0df7108 chore: remove leftover debug scripts and stale docs
Delete dead dev scratch (debug_python_ast*.js, test_python_inheritance.js),
the obsolete tree-sitter-dart native patch (Dart loads via WASM now and the
package is no longer a dependency), and orphaned docs superseded by the
current code and the agent-eval skill (IMPLEMENTATION_PLAN.md,
DELPHI-SUPPORT.md, run-interactive-test.md).

Colby Mchenry 948b287536 feat(frameworks): add NestJS support (#220) (#225)
Detect NestJS projects and emit `route` nodes (each linked by a `references`
edge to its handler method) across all four transport layers:

- HTTP controllers: @Controller prefix joined with
  @Get/@Post/@Put/@Patch/@Delete/@Head/@Options/@All
- GraphQL resolvers: @Query/@Mutation/@Subscription
- Microservices: @MessagePattern/@EventPattern
- WebSocket gateways: @SubscribeMessage (prefixed with gateway namespace)

Detected from any @nestjs/* dependency in package.json (falls back to scanning
*.controller.ts/*.resolver.ts/*.gateway.ts). Handles class+method path joining
with empty @Controller()/@Get(), a string-aware balanced-paren arg reader so
GraphQL type thunks (@Query(() => [User])) aren't truncated, stacked decorators
(@UseGuards) when locating the handler, and disambiguates the @Query() GraphQL
method decorator from the REST @Query() param decorator (GraphQL only counts
inside @Resolver classes). Also resolves injected *Service/*Controller refs to
their classes by Nest file-naming convention.

Adds 18 framework tests; updates the README framework table and CHANGELOG.

Colby Mchenry f5bbc26c60 perf(mcp): answer-directly steering — ~35% cheaper, ~70% fewer tool calls (#224)
* perf(mcp): steer agents to answer directly instead of delegating to subagents

CodeGraph beats native grep/read on cost only when the agent queries it
directly. When the agent delegates to file-reading sub-agents, those
sub-agents read files regardless of the index, so CodeGraph becomes net
overhead on top of the reads. The install templates even told agents to
"spawn a subagent for explore-class questions" — the expensive path.

Changes:
- server-instructions + both install templates: add an "Answer directly —
  don't delegate exploration" directive; reposition codegraph_explore as the
  efficient one-call multi-symbol tool (was: "spawn a subagent for it").
- codegraph_explore: hard-cap output to its adaptive budget (it overran,
  ~30k vs a 28k cap) and tighten the medium tier (28k->13k).
- codegraph_node: return a member outline for container kinds instead of the
  full class body.

Rigorous N>=4-per-arm warm-block benchmark (median total_cost_usd):
  excalidraw (~600 files):  WITH $0.54 vs native $1.02  (-47%)
  vscode     (~10k files):  WITH $0.41 vs native $0.72  (-42%)
  ky         (~25 files):   WITH $0.46 vs native $0.44  (wash)
Answers were equal-or-better (correct, file:line-cited) with ~6x fewer tool
calls; the directive drove the direct path on 14/14 codegraph runs.

* docs(readme): rebuild benchmark with real-world repos + cost/token/time/tool savings

Replace the "Claude Code (Python+Rust/Java)" rows — which benchmarked the
Claude Code CLI repo, not real codebases in those languages — with real
open-source projects per language: Django (Python), Tokio (Rust), OkHttp
(Java), Gin (Go), plus Alamofire (Swift) and the existing TypeScript repos
(VS Code, Excalidraw).

The table now reports all four savings the change targets — cost, tokens,
time, tool calls — as the median of 4 runs per arm (Claude Opus 4.7,
headless claude -p, with vs empty MCP config). Averages across the 7 repos:
35% cheaper, 59% fewer tokens, 49% faster, 70% fewer tool calls. Adds a
methodology note and raw WITH->WITHOUT medians.

Colby Mchenry a47355780b fix(sync): stop reporting git-untracked files as pending after sync (#206) (#218)
Both git fast-paths in ExtractionOrchestrator (sync and getChangedFiles)
classified every untracked (`??`) file as "added" without checking the
index. Indexing a file doesn't make git track it, so the file stayed `??`
and was re-reported as pending and re-indexed on every run: `codegraph
status` listed it under Pending Changes forever and each `sync` re-added
it, even though its symbols were already queryable.

Merge the modified + added handling into a single hash-compared loop so
untracked files get the same treatment as tracked ones: "added" only if
missing from the index, "modified" if contents changed, skipped otherwise.
The non-git fallback path already did this and is unchanged.

Closes #206. Reported by @15290391025.

`codegraph init -i` from a git super-repo containing independent nested
git repositories (not submodules) reported "No files found to index":
git ls-files reports an embedded repo only as an opaque `subdir/` entry
and never lists its files. Detect embedded repos via that trailing-slash
signal and recurse `git ls-files` into each, indexing tracked + untracked
source and honoring each repo's own .gitignore.

Colby Mchenry 9b06b0edde fix(db): require better-sqlite3 ^12.4.1 so Node 24 gets the native backend (#203) (#216)
better-sqlite3 ^11.0.0 (latest 11.10.0) ships no prebuilt binary for
Node 24's ABI (node-v137) and predates Node 24, so every Node 24 install
silently fell back to the 5-10x-slower WASM backend. Bump to ^12.4.1 —
the first 12.x with the Node 24 prebuild — and raise the engines floor to
Node 20 (Node 18 is EOL and dropped from better-sqlite3 12.x prebuilds).

Verified on macOS Node 24.15.0 (ABI 137): prebuilt binary used with no
compiler (installs even with CC/CXX sabotaged), `codegraph init -i` shows
no WASM banner, and `codegraph status` reports Backend: native. 639/639
tests pass on Node 22.

Colby Mchenry 1cd162a66d fix(mcp): auto-detect project via roots/list when no rootUri (#196) (#214)
MCP tools failed with "CodeGraph not initialized" when a client launched
the server outside the project and sent no rootUri/workspaceFolders — the
server fell back to its own cwd, missed the project's .codegraph/, and
returned a misleading "run codegraph init" error on every call. The only
workaround was passing projectPath by hand to each tool.

When no explicit path is given, the server now asks the client for its
workspace root via the standard MCP roots/list request (gated on the
client advertising the roots capability) before falling back to cwd. This
required teaching the stdio transport to send server->client requests and
match their responses by id (previously responses were dropped as invalid).

When a project still can't be resolved, the error now names the directory
it searched and tells the user to pass projectPath or add --path to the
MCP config, instead of pointing at a re-init they don't need.

Colby Mchenry cf7db7cb98 fix(mcp): skip fs.watch on WSL2 /mnt drives that hang MCP startup (#199) (#210)
Recursive fs.watch on a WSL2 /mnt NTFS/9p mount walks the directory tree
with every readdir/stat crossing the Windows boundary, stalling the event
loop long enough to blow past opencode's 30s MCP handshake timeout so the
tools never appear. This is the file-watcher half of the #172 fix, which
moved the DB/WASM open off the handshake but left the watcher on the
critical path.

- Add watchDisabledReason() policy: CODEGRAPH_NO_WATCH (off) >
  CODEGRAPH_FORCE_WATCH (force on) > WSL2 + /mnt auto-detect (off).
  FileWatcher.start() and the MCP server both honor it; the server now
  logs why watching is off and how to refresh.
- Add `codegraph serve --mcp --no-watch`.
- When watching is off, init/install offer git sync hooks (post-commit,
  post-merge, post-checkout) that run `codegraph sync` in the background,
  or fall back to manual sync; either way the user is told the index
  stays frozen until re-synced. uninit removes the hooks.
- Tests: watch-policy + git-hooks (idempotency, user-content preservation,
  core.hooksPath).

Root-cause analysis and workaround by @mengfanbo123.

Colby Mchenry 79b9601aae fix(installer): write Claude project-local MCP config to .mcp.json (#207) (#209)
Project-local installs wrote the MCP server to ./.claude.json, which Claude Code never reads — project-scoped servers must live in .mcp.json. The codegraph tools silently never loaded until users renamed the file by hand. Local installs now write ./.mcp.json and migrate any stale ./.claude.json entry on install and uninstall (siblings preserved). Global installs (~/.claude.json, user scope) were already correct.

Colby McHenry 7fe64b32be feat(eval): add agent-eval harness and /audit + /publish Claude skills
Replaces the old interactive publish.js script with two Claude skills and
a full agent-evaluation harness:

- `.claude/skills/audit/` — `/audit` skill drives `scripts/agent-eval/audit.sh`
  to benchmark retrieval quality (with vs. without codegraph) on a chosen
  real-world repo from the new `corpus.json` (17 repos across 14 languages).
- `.claude/skills/publish/` — `/publish` skill orchestrates the full release
  workflow (preflight → changelog → confirmation gate → bump/build → npm
  publish → GitHub release), replacing `publish.js`.
- `scripts/agent-eval/` — headless (`run-agent.sh`, `run-all.sh`) and
  interactive tmux (`itrun.sh`) harnesses with stream-json parsers
  (`parse-run.mjs`, `parse-session.mjs`) that report tool calls, token
  usage, and a VERDICT line summarising codegraph_explore vs. Read/Grep counts.
- `run-interactive-test.md` — documents the two harnesses, idle-detection
  approach, and what "good" agent behavior looks like after explore-first
  guidance.

Colby Mchenry 2c1a314b84 feat(mcp): line numbers in explore output + per-file cluster fixes (#188)
* feat(mcp): line numbers in explore output + per-file cluster fixes

Follow-up to #185. Three changes to codegraph_explore:

1. Source sections now carry cat -n style line-number prefixes
   (<num>\t<code>), so the agent can cite file:line straight from the
   payload instead of re-Reading the file just to recover a line number.
   Isolated A/B: the no-line-numbers arm spent 2 Reads + a grep to find a
   line number the line-numbered arm cited with zero follow-up calls.
   Payload cost ~3-5%. Toggle off with CODEGRAPH_EXPLORE_LINENUMS=0.

2. Per-file cluster selection now ranks clusters containing a query entry
   point ahead of dense declaration blocks. Density-only ranking buried
   the relevant methods (perform/didCreateURLRequest/task in Alamofire's
   Session.swift) under the top-of-file class header + property list.

3. Whole-file "envelope" nodes (a class/struct/etc. spanning >50% of the
   file) are excluded from clustering. The Session class spans ~1,400
   lines; keeping it collapsed every method into one giant cluster that
   tail-trimmed down to just the class header, hiding the methods.

Net vs the 0.7.10 baseline, line numbers on: Alamofire -60%, Excalidraw
-32%, VS Code -12% per explore call.

* fix(mcp): language-neutral omission markers in explore output

The gap separator and the two tail-trim markers used C-style `//`
comments, which aren't comments in Python, Ruby, etc. Switch to plain
`... (gap) ...` / `... (trimmed) ...` so they read correctly inside any
language's fenced source block. With line numbers on, the line-number
jump already corroborates a gap.

* fix(mcp): language-neutral truncation marker in codegraph_context

Sibling to the explore marker fix: codegraph_context's code-block
truncation used a C-style `// ... truncated ...`. Switch to
`... (truncated) ...` so it reads correctly in any language's fenced
source block.

Colby Mchenry 93e53e7c69 feat(mcp): size-adaptive output budget for codegraph_explore (#185) (#187)
Output is now scaled to indexed file count. Small projects (<500 files)
cap at ~18KB and skip the "Additional relevant files" / completeness /
explore-budget reminders that earn their keep on larger codebases; medium
(<5,000) caps at ~28KB; large (<15,000) keeps the historical ~35KB; very
large goes up to ~38KB.

A per-file char cap also prevents a single file with many adjacent
symbols from collapsing into one whole-file dump (the pathological
Alamofire `Session.swift` case reported in #185), and a per-file symbol-
list cap stops the `#### path — sym(kind), ...` header from leaking
multi-KB lists when many adjacent symbols cluster together.

Measured against the README's benchmark repos: Alamofire (~100 files)
~62% smaller per call, Excalidraw (~600 files) ~35%, VS Code (~10k
files) ~14%. Agent-trust floor preserved — Relationships, scored cluster
selection, and structured-source output are all retained.

Colby Mchenry 4bb95639ca chore(release): refine release-notes extractor (#181)
Three fixes prompted by retroactively unwrapping the 0.7.6 / 0.7.7 /
0.7.9 release notes:

- Add `--stdin` mode so the extractor can clean up an existing release
  body (via `gh release view ... --json body --jq '.body'`) without
  needing a matching CHANGELOG.md entry. The 0.7.9 release didn't have
  one — its body had been hand-rolled from the 0.7.8 entry on publish.

- Stop treating `+` as a bullet marker. CommonMark allows it, but our
  CHANGELOG uses literal `+` inline (`MCP config + instructions`) and
  the script was misreading those as nested bullets. Keep `-`, `*`,
  and `N.` only.

- Preserve fenced code blocks verbatim. The 0.7.6 entry has a triple-
  backtick ```bash block; the previous pass was joining its lines into
  one, producing unreadable code.

Colby Mchenry 483ec9171c chore(release): unwrap CHANGELOG paragraphs for GitHub Release notes (#180)
GitHub renders release-note Markdown with GFM hard breaks, so every
`\n` becomes `<br>`. The CHANGELOG is hard-wrapped at ~75 chars for
readable diffs, which renders as awkward visible line breaks on the
release page (see https://github.com/colbymchenry/codegraph/releases/tag/v0.7.10).

Add `scripts/extract-release-notes.mjs` to extract a version block
and join indented continuation lines into a single line per bullet.
Nested list items, headings, and link references are preserved.
`scripts/release.sh` now uses this helper instead of the inline awk
extractor — repo-level CHANGELOG.md viewing is unaffected because
CommonMark there treats newlines as spaces.

Also fix the 0.7.10 entry: "Two underlying fixes" -> "Three", "Rust
file-/level" broken hyphen, and move the closes/credit line above
the nested list so it doesn't strand as a top-level paragraph.

Colby McHenry fb8fb0ea8b release: 0.7.10 (Windows mojibake fix, module-qualified symbol lookups, MCP handshake) v0.7.10 2026-05-19 11:32:47 -05:00
Colby Mchenry 83f36dc170 fix(mcp): resolve module-qualified symbol lookups (#173) (#179)
`codegraph_callees stage_apply::run` (and `_node`, `_impact`, ...)
returned "not found" against a repo with 7-9 sibling Rust modules,
each exporting `pub async fn run`. Two underlying issues:

1. The FTS5 query builder stripped `:` as a special char without
   splitting on `::`, so `stage_apply::run` collapsed to the literal
   `stage_applyrun` which matches nothing. Treat `::` as whitespace
   before the strip step so both halves become FTS tokens.

2. `matchesSymbol` only understood `Parent.child` qualifiers and
   relied on `qualifiedName` carrying the module path. Rust file-
   level functions don't have their module name in `qualifiedName`
   (it's encoded in the file path instead), so even dot-style
   lookups failed. Accept `::`, `.`, `/` as separators; multi-level
   forms compose; Rust `crate::`/`super::`/`self::` prefixes get
   stripped before path matching. Fall back to file-path containment
   when the qualified-name suffix doesn't match — `stage_apply::run`
   matches a `run` in any file whose path has a `stage_apply` segment.

Also tightens the no-match branch: qualified lookups no longer fall
through to a fuzzy text match. `stage_apply::nonexistent_fn` returns
`null` instead of silently resolving to an unrelated `rollback` in
the same file.

Colby Mchenry e176062c56 fix(cli): ASCII glyph fallback for Windows console mojibake (#168) (#178)
The shimmer progress renderer writes from a worker thread via
`fs.writeSync(1, ...)` to keep the animation smooth while the main
thread is busy in SQLite. That path bypasses Node's TTY-aware
UTF-8->codepage conversion on Windows, so glyphs like `|`/`<>`/`-`
were emitted as raw UTF-8 bytes and reinterpreted by the console's
OEM codepage (CP437, CP936, ...), producing strings like
`鋍?[0m 鉒?[0m Scanning files 鈥?N found`.

Add `src/ui/glyphs.ts` with `supportsUnicode()` detection plus
matched Unicode + ASCII glyph sets, and route all CLI/shimmer
output through `getGlyphs()`. Defaults: ASCII on Windows and on
Linux kernel consoles (`TERM=linux`), Unicode everywhere else.
`CODEGRAPH_UNICODE=1` and `CODEGRAPH_ASCII=1` are escape hatches.

Colby Mchenry 36c8dbc404 fix(mcp): don't block initialize handshake on heavy init (#172) (#177)
The MCP `initialize` handler was awaiting `tryInitializeDefault` —
which opens the SQLite DB and runs `await initGrammars()` (tree-sitter
WASM bootstrap) — before sending the JSON-RPC response. On slow
filesystems (Docker Desktop VirtioFS on macOS, WSL2) this could exceed
Claude Code's ~30s handshake timeout, leaving the codegraph child
process alive and unresponsive with no tools visible in the client.

Send the response first; defer the open to a tracked background
promise. The lazy retry path used by `tools/list` and `tools/call`
now awaits that promise instead of racing it with `openSync`, so we
never double-open the SQLite file.

Adds a subprocess-based regression test that asserts the JSON-RPC
response arrives on stdout before `startWatching()` logs to stderr.
This ordering check catches the regression on any filesystem, not
just slow ones where the timing matters in practice.

Reported by @sashanclrp; isolated by @sgrimm's wire capture.

* release: 0.7.7 (multi-agent installer — Cursor, Codex, opencode)

* fix(installer): opencode .jsonc + AGENTS.md (0.7.8)

v0.7.7 wrote ~/.config/opencode/opencode.json, but opencode reads
opencode.jsonc by default — so the codegraph MCP entry never appeared
in any opencode session. Also installs AGENTS.md so opencode's model
reaches for codegraph_* tools instead of native Grep.

- Prefer existing .jsonc, fall back to .json, default new installs
  to .jsonc.
- Surgical edits via jsonc-parser preserve user comments and
  formatting across install / re-install / uninstall round-trips.
- Install AGENTS.md (global ~/.config/opencode/AGENTS.md, local
  ./AGENTS.md) with the shared INSTRUCTIONS_TEMPLATE — same
  marker-delimited approach Codex uses.
- +9 opencode-specific tests covering filename precedence, comment
  preservation, AGENTS.md install + sibling-content preservation,
  uninstall reverses both files.

575/575 tests pass. Hand-verified end-to-end: opencode session calls
codegraph_node + codegraph_callers for a structural query, zero Grep
calls.

* docs: overhaul CLAUDE.md and add scripts/release.sh + Cursor rules file

Replaces the old Claude-only CLAUDE.md with a comprehensive guide covering
the full project architecture, multi-agent installer, test conventions,
NodeKind/EdgeKind reference, and release workflow. Key additions:

- Documents the layered pipeline, all module paths, and the multi-target
  installer (targets/, registry.ts, AgentTarget interface).
- Adds the Cursor `--path` quirk and the "update all three surfaces" rule
  when changing MCP tool guidance.
- Documents `npm run eval`, `test:eval`, and the full set of build/test
  commands including single-file patterns.
- `scripts/release.sh` — idempotent bash script that tags the current
  commit, pushes the tag, and creates a GitHub Release whose notes are
  extracted from the matching `## [X.Y.Z]` block in CHANGELOG.md. Safe
  to re-run after partial failure.
- `.cursor/rules/codegraph.mdc` — Cursor-specific agent instructions
  (tool decision table, rules of thumb, index-lag warning) written by
  the installer and kept in sync with server-instructions.ts and
  instructions-template.ts.

Colby Mchenry a447e1d430 feat(installer): multi-target — Claude Code, Cursor, Codex CLI, opencode (#162)
* feat(installer): multi-target — Claude Code, Cursor, Codex CLI, opencode

Closes the Claude-locked installer behind issue #137. The runtime MCP
server was already agent-agnostic (stdio); only the installer was
locked. After this refactor, `codegraph install` can write per-agent
MCP config + instructions for any combination of supported agents.

## What ships

Four agent targets, each implementing the new `AgentTarget` interface:

- **Claude Code** — `~/.claude.json`, `~/.claude/settings.json`,
  `~/.claude/CLAUDE.md` (or local equivalents). Behavior preserved
  from the original installer; existing installs upgrade in place.
- **Cursor** — `~/.cursor/mcp.json` (g) or `./.cursor/mcp.json` (l)
  + project-local `./.cursor/rules/codegraph.mdc`.
- **Codex CLI** — `~/.codex/config.toml` with `[mcp_servers.codegraph]`
  + `~/.codex/AGENTS.md`. Global only. Hand-rolled TOML serializer
  scoped to the table we own — siblings + array-of-tables preserved.
- **opencode** — `~/.config/opencode/opencode.json` (XDG) or
  `./opencode.json`.

Adding a 5th agent is a new file in `src/installer/targets/` plus
one entry in `registry.ts`.

## CLI changes

```
codegraph install                                   # interactive multi-select
codegraph install --yes                             # auto-detect, install global
codegraph install --target=cursor,claude --yes     # explicit list
codegraph install --target=auto --location=local   # detected, project-local
codegraph install --target=none                    # skip agent writes entirely
codegraph install --print-config codex             # dump snippet, no writes
```

## Backwards compat

Every export from the old `config-writer.ts` (`writeMcpConfig`,
`writePermissions`, `writeClaudeMd`, `hasMcpConfig`, `hasPermissions`,
`hasClaudeMdSection`) is preserved as a `@deprecated` shim that
delegates to per-file helpers in `targets/claude.ts`. Existing Claude
users see byte-identical on-disk layout — `detect()` reports
`alreadyConfigured: true`, re-running is a no-op.

## Tests

+47 new tests in `__tests__/installer-targets.test.ts`:
- Parameterized contract test across all 4 targets × supported
  locations (install → unchanged on re-run, sibling preservation,
  uninstall reverses install, printConfig writes nothing).
- Codex partial-state recovery, locked-block contract for the
  codegraph table, full TOML serializer suite.
- Registry: getTarget, resolveTargetFlag (auto/all/none/csv).

`__tests__/installer.test.ts` relaxed one assertion: the new code
returns `unchanged` for byte-identical re-runs instead of `updated`;
the surrounding-custom-content contract is unchanged.

## Uninstall behavior change

`bin/uninstall.ts` now loops `ALL_TARGETS.uninstall('global')` on
`npm uninstall -g`. A user who manually configured
`~/.codex/config.toml` with our block will have only that block
removed on package uninstall — we only touch the dotted-key table
we own.

Based on andreinknv/codegraph@c5165e4. Issue #137.

* chore(scripts): add local-install.sh for hands-on branch testing

Builds the current branch and `npm link`s it as the global
`codegraph` binary. `--undo` unlinks and reinstalls the published
version. Mirrors the style of scripts/release.sh.

* feat(installer): move agent picker to the first prompt

Reorders runInstallerWithOptions so the multi-select for agents
(Claude / Cursor / Codex / opencode) is step 1 — before the
global-npm-install confirm and before the location prompt. Bare
`npx @colbymchenry/codegraph` now opens with "Which agents should
CodeGraph configure?", which is the answer most users want first.

Side effects of the reorder:

- Early exit if zero targets selected — skips global-install and
  location prompts entirely, exits with "nothing to do."
- Multiselect labels drop the per-location "will skip" hint (location
  isn't known yet) and replace it with a static "global only" badge
  for targets like Codex that have no project-local config concept.
- If every selected target is global-only, the location prompt is
  skipped and global is forced (no point asking).
- Detection probes the user-provided location if known via flag,
  else 'global' as the most common default — labels are a hint
  about what's installed locally, not load-bearing.

* fix(installer): disambiguate "global" wording in install prompts

Two prompts both said "global" but meant different things — users
read them as duplicates. Renamed for clarity:

- Step 2 (npm install -g): "Install codegraph globally?" →
  "Install the codegraph CLI on your PATH? (Required so agents can
  launch the MCP server)". Spinner messages match.
- Step 3 (config location): "Where would you like to install?" with
  "Global"/"Local" → "Apply agent configs to all your projects, or
  just this one?" with "All projects" (~/.claude, ~/.cursor, etc.)
  / "Just this project" (./.claude, ./.cursor, etc.).
- All-global-only fallback: "Using global install" → "Writing
  user-wide configs (selected agents have no project-local config)."

Underlying `Location` values ('global' / 'local') unchanged; only
the UI strings shift, so no test or flag breakage.

* fix(installer/cursor): inject --path so workspace-aware queries work

Cursor launches MCP-server subprocesses with cwd != workspace root,
AND does not pass rootUri or workspaceFolders in the MCP initialize
call. The codegraph MCP server's process.cwd() fallback misses the
workspace's .codegraph/ and reports "not initialized" on every tool
call. Codex and Claude don't have this issue (Codex launches with
cwd=workspace, Claude passes rootUri).

Fix: inject `--path` into the args we write for Cursor.

- local install (./.cursor/mcp.json): hardcode the absolute project
  path — known at install time.
- global install (~/.cursor/mcp.json): use `${workspaceFolder}` so
  Cursor expands it per-workspace. One global config now drives
  every project the user opens, without per-project re-install.

No test breakage — the parameterized contract tests check
idempotency / sibling preservation, not the exact args content.
File-header comment documents the rationale so the next person
doesn't strip the arg as boilerplate.

* feat(init): auto-wire project-local agent surfaces

Closes the global-Cursor UX gap: `~/.cursor/mcp.json` registers the
MCP server, but Cursor's agent only learns to *prefer* codegraph
over native grep when it sees `.cursor/rules/codegraph.mdc` — a
project-local file that global install can't write. Previously the
user had to re-run `codegraph install --target=cursor --location=local`
for every new project. Now `codegraph init` does it automatically.

## What changed

- New optional `AgentTarget.wireProjectSurfaces()` returning a
  WriteResult of project-local files to drop. Most targets omit
  it (their global config is complete). Cursor implements it to
  write the rules file.
- New `wireProjectSurfacesForGlobalAgents()` orchestrator in
  installer/index.ts — iterates ALL_TARGETS, detects which are
  configured globally, calls their wireProjectSurfaces, returns
  what was written.
- `codegraph init` calls the orchestrator in both branches:
  - Fresh init: write surfaces after CodeGraph.init succeeds.
  - Already-initialized re-init: write surfaces too, so re-running
    `init` is the documented recovery path for a project missing
    its rules file.

## Steady-state UX

  1. Once, ever: `codegraph install` (writes global agent configs)
  2. Per project: `codegraph init -i` (builds the index + auto-wires
     project-local agent surfaces — currently Cursor's rules file)

No new tests — wireProjectSurfaces delegates to writeRulesEntry,
which is already covered by the parameterized contract tests.

* feat(installer): agent-agnostic instructions template

The old template was inherited from the Claude-only era and
prescribed "ALWAYS spawn an Explore agent" — a Claude Code-specific
concept (subagents via the Task tool). When Cursor's agent read
this it had no Explore agent to spawn, got confused, and fell back
to native grep/read even for structural queries the codegraph MCP
tools answer in one call.

This rewrite:

- Frames each tool by the question it answers (search vs callers
  vs impact vs context vs explore vs node vs files vs status).
- Tells the agent explicitly to TRUST codegraph results and not
  re-verify them with grep — the over-grep-after-codegraph
  behavior was the main symptom we saw on Cursor.
- Reframes "spawn Explore agent" as an OPTIONAL pattern for
  harnesses that support parallel subagents — Claude Code still
  gets the hint, Cursor / Codex / opencode just skip it.
- Trims the "if not initialized" section to one prescriptive line.

Same marker delimiters (`<!-- CODEGRAPH_START/END -->`) so existing
installs upgrade in place via the marker-based section swap. No
test changes needed — the parameterized contract tests check
marker placement + sibling preservation, not the literal body.

Effective surfaces: ~/.claude/CLAUDE.md (Claude), .cursor/rules/
codegraph.mdc (Cursor, project-local), ~/.codex/AGENTS.md (Codex).
Users get the new copy by re-running `codegraph install` for
global writes, or `codegraph init` for Cursor's project rules.

* docs(readme): reflect multi-agent support at the top + accurate flow

- Tagline now reads "Supercharge Claude Code, Cursor & Codex" instead
  of Claude-only — multi-agent support is what the PR is about, the
  README should say so above the fold.
- New badge row (Claude Code / Cursor / Codex CLI / opencode) in the
  same shields.io style as the OS row.
- Install-flow bullets reordered to match the actual prompt order
  (agent picker first, then PATH install, then location).
- `codegraph init -i` step now mentions that init wires up
  project-local agent surfaces (Cursor rules file etc.) so global
  install works in every project without a re-run.
- Agent-agnostic phrasing in the closing line ("your agent" not
  "Claude Code").

Headline-level brand decision left intentionally in this PR — the
existing Claude-only positioning predates multi-agent support.

Colby McHenry 7e617d819b release: 0.7.6 (fix permission denied on global install)
The 0.7.5 tarball shipped `dist/bin/codegraph.js` without the executable
bit set, causing `zsh: permission denied: codegraph` after a fresh global
install. The build script now `chmod +x`'s the binary before packing.

Also adds CHANGELOG.md and documents the release workflow in CLAUDE.md.

* feat(rust): expand cargo workspace member globs and trust workspace hits

- Parse glob entries in `[workspace].members` (e.g. `crates/*`,
  `helix-*`) via picomatch against a new optional
  `ResolutionContext.listDirectories` so workspaces that don't
  enumerate every member are covered. Implementation walks the
  static-prefix subtree with a depth cap and skips `target`,
  `node_modules`, `.git`, etc.
- Bump Pattern 4's confidence to 0.95 when the workspace map
  produces a hit. The cargo manifest gives an unambiguous
  crate-name -> crate-root mapping, so workspace-driven module
  resolution should beat name-matcher's self-file matches
  (otherwise every file with `use foo::...` self-resolves at 0.7
  and the cross-crate edge never materializes).
- Validated against astral-sh/uv (`members = ["crates/*"]`,
  67 crates, 567 .rs files): 1,969 cross-crate `imports` edges
  reaching 60 distinct member lib.rs files, up from 0.

Colby Mchenry 1cbd5a8123 fix(extraction): recurse into git submodules when listing files (#150)
`git ls-files -co --exclude-standard` only sees the submodule pointer in
the main repo's index, so projects using submodules indexed 0 files. Now
the tracked list runs with `-c --recurse-submodules` so submodule
contents are included; untracked files are gathered with a separate
`-o --exclude-standard` call (the two flags can't be combined — git only
supports --recurse-submodules with --cached/--stage).

Fixes #147.

Colby Mchenry b47c9562ec fix(cli): hard-exit on Node 25.x instead of soft warning + crash (#149)
The Node 25.x V8 turboshaft WASM JIT Zone allocator bug
(https://github.com/colbymchenry/codegraph/issues/81) reliably crashes
CodeGraph mid-indexing with `Fatal process out of memory: Zone` when
tree-sitter grammars get JIT-compiled. We already had:

- `engines: "node": ">=18.0.0 <25.0.0"` in package.json
- Lazy grammar loading (#61)
- A startup `console.warn` when Node 25+ is detected

But the recurring duplicates (#54, #81, #140, plus comments from
multiple unique users) show those defenses aren't enough:

- npm `engines` is a soft warning by default, so `npm install -g`
  doesn't block.
- The startup `console.warn` is a single yellow line that scrolls
  off-screen before the OOM 30 seconds later, so users connect the
  crash to "CodeGraph is broken" rather than "I'm on the wrong Node
  version" and file a fresh issue.

This patch turns the soft warning into a hard exit. On Node 25+ we
print a bordered banner that names the V8 root cause, embeds the
detected version, gives Node 22 LTS install commands (nvm + Homebrew),
and links to #81 — then exit(1) BEFORE any tree-sitter import
triggers WASM JIT. The previous behaviour is preserved behind
`CODEGRAPH_ALLOW_UNSAFE_NODE=1` for anyone who patched V8 themselves
or wants to test a future Node 25 fix.

The banner builder is extracted to `src/bin/node-version-check.ts` so
the test can import it without triggering CLI bootstrap. Five unit
tests pin the version interpolation, root-cause explanation, recovery
commands (nvm + brew), override env var, and #81 link — these are
load-bearing and shouldn't get edited away silently.

Suite: 509 → 514, all passing. Verified both paths manually by
flipping the threshold to 22 in dist and running on Node 22.20.0:
without the env var the CLI prints the banner and exits 1; with
`CODEGRAPH_ALLOW_UNSAFE_NODE=1` it prints the banner and continues.

Colby Mchenry 55daeffe13 fix(db): surface SQLite backend in status + actionable WASM-fallback banner (#148)
Closes the visibility gap behind issues #138 (WASM-on-macOS) and #139
(MCP "database is locked"). `better-sqlite3` is in optionalDependencies,
so when the native build fails npm install still succeeds and the
runtime silently falls back to node-sqlite3-wasm — 5-10x slower and
without WAL, so writers block readers (which is what makes the MCP
server appear to "lock the DB" in #139). The only existing signal was
a one-line `console.warn` to stderr that MCP transports typically
swallow.

This patch does NOT change install behavior — better-sqlite3 stays in
optionalDependencies so cross-platform installs keep working. It just
makes the substitution observable + recoverable.

## Visibility (4 surfaces)

- CLI `codegraph status`: new `Backend:` line under Index Statistics.
  `native` rendered green; `wasm` rendered yellow with an inline
  `npm rebuild better-sqlite3` nudge. Also exposed in `--json` as
  `backend: 'native' | 'wasm'`.
- MCP `codegraph_status`: new `**Backend:**` line. Native form reads
  `native (better-sqlite3)`; wasm form prepends a warning glyph and
  includes the full fix recipe.
- Stderr banner on fallback (`buildWasmFallbackBanner`): replaces the
  bare one-line `console.warn` with a multi-line bordered banner
  covering macOS + Linux fix steps and optionally appending the
  native load error.
- README troubleshooting: new "Indexing is slow / MCP database is
  locked / WASM fallback active" entry that walks users to the
  `Backend:` line and the fix.

## Per-instance backend tracking

`createDatabase` previously set a module-level `activeBackend` global.
MCP can open multiple project DBs in one process via the
`getCodeGraph()` cache, so the global would race / overwrite. Refactor:
`createDatabase` now returns `{db, backend}`, `DatabaseConnection`
carries `private backend` and exposes `getBackend()`, and
`CodeGraph.getBackend()` is the public surface. The CLI and MCP both
call `cg.getBackend()`.

## What this does NOT fix

The root cause of users landing on WASM is environment-specific (Mac
without Xcode CLT, Node version mismatch, etc.) and not fixable in
code without changing the optionalDependencies design. The README
entry tells users what to run; `Backend: native` after rebuild is the
confirmation signal.

## Tests

New `__tests__/sqlite-backend.test.ts` (6 tests) pins the banner
recipe content (so future edits can't strip the recovery commands),
the `WASM_FALLBACK_FIX_RECIPE` constant, and per-instance
`DatabaseConnection.getBackend()` / `CodeGraph.getBackend()` reporting.
Suite: 503 → 509, all passing.

Credit to @andreinknv whose analysis on #138 (and patches on his fork
at 6d0e7a2 + 69f7001) framed the visibility approach.

* feat(extraction): run framework extractors after tree-sitter parse

* docs: document framework route extraction

* feat(strip-comments): add per-language comment stripper for framework extractors

Replaces comment characters and string-literal contents with spaces (not
removal) so source offsets stay valid for downstream regex match index ->
line number conversion. Handles Python triple-quoted docstrings, Ruby
=begin/=end, Rust nested block comments, and the standard //, #, /* */
forms across the supported languages.

This is consumed by framework extract() methods in a follow-up commit so
that commented-out / docstring routing examples don't surface as phantom
route nodes in the graph.

* feat(frameworks): strip comments before regex extraction (prevents phantom routes)

Pipes the per-language stripCommentsForRegex helper into every framework
extract() that scans raw source: django/flask/fastapi (python.ts),
express, laravel, rails, spring, go, rust, aspnet, vapor, plus
swiftui/uikit struct extraction in swift.ts.

Without this, examples like:

    # path('/admin/', AdminPanel.as_view())
    """ path('/users/', UserListView.as_view()) """
    urlpatterns = [path('/real/', RealView.as_view())]

produced 3 phantom route nodes. Now only the real one is extracted.

Each framework gets a regression test in __tests__/frameworks.test.ts
asserting that line-, block-, docstring- and (where relevant)
heredoc-style commented-out routes do not surface as nodes.

Colby Mchenry 804ab671d4 feat(mcp): emit server-level instructions in initialize response (#143)
Adds a universal tool-selection playbook surfaced by MCP clients
(Claude Code, Cursor, opencode, LangChain, OpenAI Agent SDK) in the
agent's system prompt automatically. Without this, agents have to
infer tool composition from individual tool descriptions and tend to
walk callers manually instead of reaching for codegraph_impact, etc.

Scoped tight: only the 9 tools that exist on main today
(search/context/callers/callees/impact/node/explore/files/status), no
"(when present)" references to unmerged tools, no per-language
guidance. ~40 lines of useful guidance.

Salvaged from #121, which bundled the instructions with #117's MCP
tool-registry refactor and referenced many tools that don't exist on
main.

Colby Mchenry a460b856c2 perf(db): drop redundant idx_edges_source / idx_edges_target (#142)
Both narrow indexes are fully covered by the existing (source, kind)
and (target, kind) composites via SQLite's left-prefix scan, so
they're dead weight on every write. Empirical measurements (from the
spike script in PR #122 on a 50K-node / 250K-edge synthetic DB):

  - DB size: 34.7 MB → 27.0 MB (-22.2%)
  - Bulk insert (250K edges): 590ms → 431ms (1.37× faster)
  - source/target lookup latency: no regression

Adds migration v4 to drop both on existing databases; fresh-DB schema
no longer creates them.

andreinknv 153fd1e974 fix(gitignore): anchor "coverage/" rule to repo root (#127)
The unanchored "coverage/" rule (intended to ignore the test-output
directory at repo root) silently matches any "coverage/" directory in
the tree. This bit a real PR: src/coverage/ was added but never made
it into the commit because git add silently dropped the files. The
PR shipped with the test importing a module that didn't exist.

Anchor the rule to "/coverage/" so it only ignores root-level test
output, allowing src/coverage/, packages/*/coverage/, etc. to be
committed normally.

andreinknv 5e5d8d9447 fix(cli): surface lock-acquisition errors and silence Emscripten Aborted() spam (#128)
* fix(cli): surface lock-acquisition errors and silence Emscripten Aborted() spam

Two unrelated cosmetic but actively misleading bugs that surface when
the indexer is under load.

1) printIndexResult fell through to "No files found to index" whenever
   the IndexResult had filesIndexed=0 AND filesErrored=0. The
   lock-acquisition path returns success:false with a generic
   "Could not acquire file lock" entry in result.errors[] (severity
   'error'), but filesErrored counts only file-level parse failures,
   so the user saw "No files found to index" — actively wrong.
   Add a top-of-function check for the !success && !hasErrors case
   that surfaces the first severity:'error' message instead.

2) parse-worker.ts let Emscripten's stderr "Aborted()" lines (plus
   their "Build with -sASSERTIONS for more info" follow-ups) leak to
   the parent's terminal whenever a WASM tree-sitter parser crashed
   on a pathological file. Even after the JS layer caught and recovered,
   the user saw dozens of `Aborted()` lines spammed to stderr. Install
   a stderr filter at worker startup that drops only those specific
   Emscripten internal lines; everything we log ourselves passes
   through unchanged.

Verified live against ollama/ollama@v0.22.0:
  - second concurrent `codegraph index` now shows
    "Could not acquire file lock - another process may be indexing"
    instead of "No files found to index"
  - WASM-crash-prone re-index produced 0 Aborted() lines (down from 68+).

* fix(cli): null-safe error surfacing + clearer stderr-filter contract docs

Two reviewer findings on PR #128:

- printIndexResult: when result.success is false but result.errors
  contains no severity:'error' entry (degenerate case but possible
  if the result shape ever drifts), the find() returned undefined
  and the previous if-guard fell through to the misleading
  'No files found to index' branch. Now always surfaces a clear
  failure message via clack.log.error, defaulting to 'Indexing
  failed — no further details available' when no specific error
  is in the errors list.

- parse-worker stderr filter: callback handling was already correct
  but the comment didn't document it; expand the comment to spell
  out the Writable-stream-contract obligation, the per-call match
  semantics (split-chunk caveat), and the substring-exactness
  trade-off so future readers understand the deliberate trade-offs.

andreinknv 4f6c51d381 fix(extraction): drop duplicate export-var nodes and honour maxFileSize in bulk path (#129)
Two correctness bugs in the core extraction pipeline, surfaced by an
adversarial stress corpus (5k synthetic export-const declarations
plus a deliberate 8MB single-line file):

1) Every `export const X = ...` produced TWO nodes for the same
   symbol — one kind:'variable' from extractExportedVariables, plus
   one kind:'constant' from extractVariable (called when the walker
   descended into the export_statement child). Stress test showed
   100% duplication across 5,003 export-const declarations. The
   dedicated extractVariable dispatch is the correct one — it picks
   kind from isConst, captures the initializer signature, and walks
   type annotations; the export-statement helper was redundant
   because the language extractors' isExported predicate already
   walks parent chains. Remove the export_statement branch from the
   dispatch (children are descended into normally) and drop the
   private helper.

2) The bulk indexAll path read each file's stats but never compared
   stats.size against config.maxFileSize. Vendored generated files
   (multi-MB headers, minified bundles, etc.) were indexed regardless
   of the user's size cap. The single-file extractFile path enforced
   it; only the bulk path was missing the check. Mirror the
   single-file behaviour: emit a 'size_exceeded' warning, count the
   file as skipped, advance progress, and continue.

On the stress workspace (5,005 synthetic files; 50,000 fns in one
3MB file; 8MB single-line file; 5,000 export-const declarations):

  before:  65,014 nodes (100% var/const duplication, every >1MB file
           indexed despite maxFileSize=1MB)
   after:  10,008 nodes (0 duplicates, large files correctly skipped
           with size_exceeded warnings)

Tests calibrated to the duplicate behavior were updated to look for
kind:'constant' on `export const`, which is the correct kind. Full
suite: 380 passed (was 374 passed, 6 failed before this fix).

andreinknv d151c0f922 feat(resolution): tsconfig path aliases + re-export chain following (#130)
* feat(resolution): tsconfig path aliases + re-export chain following

Two related correctness improvements that unlock accurate import
resolution on modern JS/TS codebases.

1) tsconfig/jsconfig path aliases.

The resolver previously had a hard-coded list of common aliases
(@/, ~/, src/, app/) and ignored any project-defined paths from
tsconfig.json compilerOptions.paths — which means every import
through @components/Foo, @lib/utils, etc. on Vite/Next/Nuxt/Nest
projects silently failed to resolve. Adds src/resolution/path-
aliases.ts that reads tsconfig.json (and falls back to jsconfig.json),
honours baseUrl, supports the * wildcard, and respects the priority
order of multiple replacement targets per alias. JSONC tolerant
(strips comments + trailing commas, common in the wild). The new
ResolutionContext.getProjectAliases() lazily loads + caches the
result; resolveAliasedImport consults it before the legacy fallback
list.

Verified live on a synthetic project with @utils/* and @lib custom
aliases: both resolved to the correct files and produced edges,
unresolved_refs empty.

2) Re-export chain following.

`import { Foo } from './barrel'` where barrel.ts only re-exports
(`export { Foo } from './real'` or `export * from './real'`) used
to fail because the resolver only looked for declarations IN the
resolved file — it never followed the export chain to the actual
definition. Adds extractReExports() (named + wildcard + as-rename
forms), a per-file getReExports() context method, and a recursive
findExportedSymbol() helper with depth cap (8) and visited-set
cycle protection. resolveViaImport now uses it whenever the symbol
isn't directly declared in the imported file.

Verified live on a synthetic 3-hop chain (main → all.ts wildcard →
index.ts named → auth.ts declaration): signIn resolved correctly,
unresolved_refs empty.

Full test suite: 380 passed, 0 failed.

* fix(resolution): address reviewer findings — isExternalImport bypass, JSONC strings, comment stripping, optional context method

Five fixes from independent semantic review:

- isExternalImport now consults context.getProjectAliases() before
  the bare-specifier heuristic. Without this, custom prefixes like
  '@components/*' from tsconfig.paths were classified as npm and
  resolveAliasedImport never even ran. Adds a context parameter
  (optional, for backward compat with mock contexts).

- stripJsonc rewritten as a string-aware state machine. The previous
  regex-only version corrupted any URL embedded in a JSON string
  value ('https://cdn.example.com' lost everything after '//').

- extractReExports now strips JS line+block comments from content
  before applying the regex, so a commented-out 'export { x } from
  ...' no longer creates a phantom re-export edge. New
  stripJsComments helper preserves string literals (single, double,
  template) so '//' inside a string stays intact.

- ResolutionContext.getProjectAliases() made optional so existing
  mock contexts in __tests__/resolution.test.ts (which TypeScript
  doesn't type-check because tsconfig excludes __tests__) don't
  throw at runtime when resolveAliasedImport hits them. Caller
  uses ?.

- Two new integration tests in __tests__/resolution.test.ts:
  * Path-alias resolution with name-collision: two pickMe() in
    different dirs, only the @utils-aliased one should be the
    call target. Asserts via getCallers on each candidate node.
  * No-tsconfig fallback: relative import still produces the call
    edge.

Full test suite: 832 passed (was 380; the increase is from the
biomarkers + LLM hooks that ship via parent branches).

* fix(resolution): allow re-export rename chains past the pre-filter

The fast pre-filter in resolveOne() bails when no symbol with the
reference name exists project-wide, which is incompatible with the
new chain-following code: a renamed re-export (`import { login }
from './barrel'` where the barrel does `export { signIn as login }
from './auth'`) intentionally calls a name that has no project-wide
declaration. The chain finds the renamed upstream symbol — but only
if resolution is allowed to run.

Add an import-mapping escape so the pre-filter only bails when the
ref also doesn't match any local import. Adds two tests covering the
3-hop wildcard chain and the named-rename branch.

andreinknv 56f6b3b485 feat(search): field-qualified queries (kind:/lang:/path:/name:) + fuzzy typo fallback (#131)
* feat(search): field-qualified queries (kind:/lang:/path:/name:) + fuzzy typo fallback

Two UX improvements that turn a free-text search into something a
real user can drive precisely.

1) Field-qualified queries.

A new query parser (src/search/query-parser.ts) splits the raw query
into structured filters and a free-text remainder:

  kind:function name:auth path:src/api authenticate

becomes
  { kinds: ['function'], nameFilters: ['auth'],
    pathFilters: ['src/api'], text: 'authenticate' }

Filters compose with the SearchOptions arg (intersection). Unknown
prefixes pass through as plain text so `query "TODO:"` keeps working.
Quoted values (`path:"my dir"`) handle whitespace. When the user
specifies only filters with no text, the search uses a filter-only
candidate scan instead of bailing out.

Recognised today:
  kind:        any NodeKind value
  lang:        any Language value (alias: language:)
  path:        case-insensitive substring of file_path
  name:        case-insensitive substring of node.name

2) Fuzzy fallback.

When BOTH FTS and LIKE return nothing AND the text is at least 3
chars, the resolver scans the distinct-name set with a bounded
Damerau-Levenshtein-style edit distance (≤2 for ≥5 chars, ≤1 for
4-char queries, off for shorter). Bounded edit-distance early-exits
once the row min exceeds maxDist, so this stays O(distinct-names *
avg-name-length) with a very low constant.

Verified live against ollama/ollama@v0.22.0:
  query "kind:function auth"          → only function-kind hits
  query "lang:go path:server route"   → Go files under server/
  query "getUssr"   (typo)            → finds getUser, SetUser
  query "confg"     (typo)            → finds Config

Full test suite: 380 passed.

* fix(search): address reviewer findings — tokenizer mid-token quotes, fuzzy fan-out cap, larger filter-only over-fetch, unit tests

Five fixes from independent review:

- parseQuery tokenizer: quotes that appear MID-token (path:"my dir/
  file") were not being recognised — only quotes at the start of a
  token were treated as quoted spans. The fixture path:"my dir"
  parsed as ['path:"my', 'dir"'] instead of ['path:"my dir"'].
  Tokeniser is now a single state machine that scans into a token
  until whitespace OR a quote, and recognises quotes anywhere within
  the token (skips to the matching close quote).

- searchNodesFuzzy: cap the per-name follow-up SQL queries at
  Math.max(limit*2, 50) AFTER edit-distance filtering. Without
  this, a project with many similar names (getUser1, getUser2...)
  could fan out far beyond limit queries before the inner-loop
  break kicks in.

- searchAllByFilters (filter-only no-text path): bumped over-fetch
  multiplier from 2× to 5× so a selective post-filter (e.g.
  path:src/very/specific/file.ts) doesn't return fewer than limit
  results despite the DB having matches.

- 23 new unit tests in __tests__/search-query-parser.test.ts:
  parseQuery covers known-field filter, lang/language alias,
  multiple kind: ORs, quoted spans (incl. mid-token), URL
  passthrough, empty-value passthrough, unknown prefix passthrough,
  unknown value passthrough, all-filters-no-text, empty input,
  20k-char input. boundedEditDistance covers identity, single
  insertion/deletion/substitution, length-difference shortcut,
  empty inputs, case-sensitivity, early-exit correctness.

Full test suite: 853 passed (up from 830).

* refactor(search): derive parser kind/lang sets from types.ts as const

Convert NodeKind and Language to runtime-iterable as const arrays
(NODE_KINDS, LANGUAGES) so the query parser imports the canonical
list instead of duplicating it. Also fix the path: JSDoc to say
substring (matches the .includes() impl).
