Neil e4bbbe045f perf(test): faster local test loop and cold-worktree changed runs (#33421)
- test:changed exits before starting Vitest when Git reports no changed files.
- Unrecorded tests beyond 100 in scope use Vitest's static import graph instead
  of all running, so a fresh worktree's first changed run no longer runs the
  whole suite (patched RecordedModulesResolver; CI does not record, unchanged).
- Bun's slow config load was the SQLite import scan statting every unit test;
  filtered runs now classify only the tests their filters can select, and the
  scan walks directories instead of fs.globSync.
- Silence the native config loader notice on every run.
- Zod's test bundle is content-addressed and reused, so a killed run leaks
  nothing; leaked per-run directories older than 6h are swept.
- build:packages skips compiling when package inputs, compiler, and dist are
  unchanged; test scripts no longer nest pnpm invocations.
