nicktrn a6bd370e42 chore: remove end-of-life v3 execution components (#4194)
v3 (engine V1) is end-of-lifed and the v3 clusters are gone, so this
removes the dead v3 execution code from the monorepo. It's the first
pass of TRI-11824 - the webapp v3 code paths are deliberately left
untouched and gated for a follow-up.

## Apps

Deletes the three v3-only execution apps and their build wiring:

- `apps/coordinator`, `apps/kubernetes-provider`, `apps/docker-provider`
- `.github/workflows/publish-worker.yml` - it built only those three;
the v4 worker publish is a separate workflow
- Their references in `.changeset/config.json`, `.cursorignore`,
`CHANGESETS.md`, `CONTRIBUTING.md`, `.server-changes/README.md`
- `pnpm-lock.yaml` regenerated to prune the apps and their app-only
dependencies (`socket.io`, `@kubernetes/client-node`, `p-queue`,
`execa`, `prom-client`, `tinyexec`)

## Core

Removes the helpers in `@trigger.dev/core` that only those apps used -
`ProviderShell`, `SimpleLogger`, the `Exec`/process helpers,
`isExecaChildProcess`, `getTextBody`, and `testDockerCheckpoint`. Each
was verified to have no remaining consumers anywhere in the repo.

Kept the helpers still used elsewhere: `ExponentialBackoff` (warm-start
client), `HttpReply`/`getJsonBody` (serverOnly http server),
`SimpleStructuredLogger` (widely used), and
`ZodNamespace`/`ZodSocketConnection` (still referenced by legacy v3
webapp code, hence the follow-up pass).

The `./v3/apps` and `./v3/serverOnly` export subpaths remain - only dead
members were trimmed from their barrels, so no `package.json` exports
changed.

## Verification

`@trigger.dev/core` builds, and `typecheck` passes for core, supervisor,
cli-v3, run-engine, redis-worker, and webapp.

Server Changes

This directory tracks changes to server-only components (webapp, supervisor, etc.) that are not captured by changesets. Changesets only track published npm packages — server changes would otherwise go undocumented.

When to add a file

Server-only PRs: If your PR only changes apps/webapp/, apps/supervisor/, or other server components (and does NOT change anything in packages/), add a .server-changes/ file.

Mixed PRs (both packages and server): Just add a changeset as usual. No .server-changes/ file needed — the changeset covers it.

Package-only PRs: Just add a changeset as usual.

File format

Create a markdown file with a descriptive name:

.server-changes/fix-batch-queue-stalls.md

With this format:

---
area: webapp
type: fix
---

Speed up batch queue processing by removing stalls and fixing retry race

Fields

  • area (required): webapp | supervisor
  • type (required): feature | fix | improvement | breaking

Description

The body text (below the frontmatter) is a one-line description of the change. Keep it concise — it will appear in release notes.

Writing guidance

These entries are public-facing - they ship verbatim in user-visible release notes. A few rules to keep them clean:

  • Write for the user, not the reviewer. Lead with what the user notices or has to do. If a reader who doesn't know the codebase can't tell what changed for them, rewrite it.
  • One sentence is usually enough. The body is the bullet in the changelog. If you need a paragraph, you're probably describing the implementation rather than the change.
  • Describe behavior, not implementation. Skip internal scopes, middleware names, library specifics, framework internals. Users care about what's different for them, not how it's wired.
  • Never name internal tools or infra. Observability stacks, internal services, infra components, monitoring backends, CI surfaces, AWS specifics - none of these belong in user-facing notes.

Before / after:

  • "The image verification step now parses the manifest's layer media types and returns a new result the finalizer rejects." (describes the wiring; a user can't act on it)
  • "Deploying with an outdated CLI could produce an image that fails to start on every run. These deploys are now stopped before going live, with a message asking you to upgrade the CLI and re-deploy." (what the user sees and does)

Lifecycle

  1. Engineer adds a .server-changes/ file in their PR
  2. Files accumulate on main as PRs merge
  3. The changeset release PR includes these in its summary
  4. After the release merges, CI cleans up the consumed files
