Fix C++ SEGV: NULL deref in LSP type resolver on large header files
...
Root cause: c_eval_expr_type_inner has 42 places accessing ptr->kind
on CBMType* pointers. Some code paths (cbm_type_substitute, internal
lookups) return NULL on unusual C++ AST shapes (deeply nested
templates, 300+ defs per file). NULL->kind = SIGSEGV.
Fix: safe_kind() inline returns CBM_TYPE_UNKNOWN for NULL pointers.
All 42 ->kind accesses in c_eval_expr_type_inner replaced.
Also: recursion depth guard (256), cbm_type_substitute returns
cbm_type_unknown() for NULL input, walk_usages/walk_env depth limits.
Verified: spdlog (previously crashed) now indexes 2526 nodes, 5518 edges.
All 2586 tests pass.

Replace vmem with mimalloc global allocator, add extraction-phase prescan, fix __init__.py QN collision
...
Memory management:
- Vendor mimalloc v2.1.9 as global allocator (MI_OVERRIDE=1 in prod)
- New mem.h/mem.c: RSS-based budget tracking via mi_process_info()
- Remove vmem.c/vmem.h (mmap-based budget tracking)
- Remove slab tier2 bump allocator (~300 LOC); >64B goes to mimalloc
- Slab tier1 pages from malloc (= mimalloc) instead of vmem
- Arena blocks from malloc instead of vmem
- Budget raised from 35% to 50% RAM (no more untracked C++ heap)
Extraction-phase prescan (eliminates disk re-reads):
- HTTP call sites: keyword check + URL extraction during extraction
- HTTP routes: decorator + source-based extraction during extraction
- Config file refs: regex scan during extraction
- httplinks: 41.8s → 13ms on Linux kernel (3,212x faster)
- configlink: 41.4s → 0.8s on Linux kernel (54x faster)
- Linux kernel fast-mode total: 2m38s → 1m18s
Bug fixes:
- __init__.py Module QN no longer collides with Folder QN
- index.ts same fix for JS/TS packages
- 13 regression tests for QN collision at FQN + extraction layers
- search_graph/search_code default limit raised from 10 to 500k
- Resolve all clang-tidy, cppcheck, and clang-format warnings
Repo cleanup:
- tree-sitter-form, tree-sitter-magma moved to tools/
- .gitignore: build/, node_modules/, graph-ui/dist/, TEST_PLAN.md

v0.5: CBM tree-sitter engine, 59 vendored language grammars
...
- Replace Go-binding tree-sitter with vendored C grammars compiled via
CGo (internal/cbm/); eliminates all Go module/linker fragility
- Add 32 new languages: Clojure, CMake, COBOL, Common Lisp, CUDA, Elm,
Emacs Lisp, Fortran, F#, GLSL, GraphQL, INI, JSON, Julia, Makefile,
Markdown, Meson, Nix, Protobuf, Svelte, Verilog, Vim Script, Vue, XML
(plus C, C#, Erlang, SQL, YAML quality improvements)
- Adaptive worker concurrency and mmap prefetch for faster indexing
- Graph buffer: batched SQLite writes for 3-5x throughput improvement
- Fix cancellation test: use 50ms timeout (pipeline now indexes 212-file
Erlang repo in ~400ms, well under the old 2s deadline)
- Fix isTestFunction: add "Test" prefix for C#, "test" prefix for Scala
