* perf(filesearch): move AsyncFzf index construction to a worker thread
`new AsyncFzf(allFiles, ...)` is misleadingly named — its constructor is
synchronous and dominates the @-picker's main-thread cost on workspaces
with >20k files (where the v2→v1 algorithm switch kicks in). It's the
remaining freeze source after PR #3214 moved the crawl onto async spawn-
based git ls-files / ripgrep / fdir.
This change hosts the AsyncFzf instance in a worker_threads worker so the
construction happens off the main thread; only completed find() results
cross the message channel. Below ~5k files the in-thread path is kept
because worker spawn + IPC overhead exceeds the construction cost there.
Notes:
- `FzfWorkerHandle.create()` awaits the worker `ready` event before
returning, so init errors surface at create() time rather than as a
surprise on the first find().
- Worker is `unref()`-ed so a mid-find @-picker doesn't pin process exit.
- `FileSearch` interface gains an optional `dispose?(): Promise<void>`
to release worker resources. `FileMessageHandler.clearFileSearchCache`
calls it so the long-running VS Code extension host doesn't accumulate
workers across watcher-triggered evictions.
- `installInProcessFzfTransport()` is provided for tests / sandboxed
environments that need to skip worker spawn entirely.
- Bundle gains a second esbuild build that emits `dist/fzfWorker.js`
alongside `dist/cli.js`; `prepare-package.js` ships it in the tarball.
- In `npm run dev` (tsx) the bundled worker file isn't on disk, so the
handle silently falls back to in-thread — acceptable for a dev script.
Closes the door on #3455's two open `FileIndexService` review items by
design: there is no `whenReady()` (handle awaits ready inside `create()`)
and there is no in-worker crawl (crawl stays on main, only fzf moves).

* fix(filesearch): address review feedback on fzf worker PR
- Fix worker thread leak in useAtCompletion: dispose previous FileSearch
instance on re-init and component cleanup
- Fix worker leak on init failure: wrap inst.ready() in try/catch with
timeout, dispose on failure
- Fix find()-after-dispose hang: reject immediately when worker is disposed
- Add limit field to FindMessage protocol to cap IPC payload before
postMessage serialization
- Add real worker_threads test coverage (spawn/find/dispose lifecycle,
concurrent finds, init failure, post-dispose rejection)

* fix(filesearch): address second round of review feedback
- Fix useAtCompletion cleanup: move dispose() to [cwd,config] effect so
it only fires on workspace change, not every keystroke/status transition
- Clear setTimeout in Promise.race on happy path to prevent timer leak
- Dispose FileSearch instances in FileMessageHandler on panel close
- Fix incorrect comment in prepare-package.js (resolveBundleDir, not URL)
- Add worker crash test: verify failAll rejects pending find() on exit
- Add RecursiveFileSearch.dispose() test in fileSearch.test.ts

* fix(core): close missing braces in formatDateForContext test
The second test case in the formatDateForContext describe block was
missing its closing `});`, causing a TS1005 parse error that broke CI
on all platforms. This was introduced upstream in
