gsxdsm aae6a6eca2 FN-7662: harden boot-smoke temp dir cleanup against macOS ENOTEMPTY races ...

Boot-smoke's post-verdict temp-dir cleanup could throw ENOTEMPTY on macOS when async writers (fsevents/Spotlight, the just-killed child) still touched the throwaway HOME/project dirs, turning an already-decided PASS into a pnpm verify:fast failure.

- Add removeTempDir() helper in scripts/boot-smoke.mjs: wraps rmSync with maxRetries/retryDelay and swallows any residual error (never throws) since cleanup always runs after the smoke verdict is decided/printed
- Replace both isolatedHome/isolatedProject rmSync call sites (exit handler and EADDRINUSE retry-port branch) with removeTempDir()
- Guard main() behind an import.meta.url === pathToFileURL(process.argv[1]) check so requiring boot-smoke.mjs from tests doesn't spawn a real server
- Add scripts/__tests__/boot-smoke.test.mjs covering ENOTEMPTY tolerance, always-failing rm, retry/backoff params, and the no-boot-on-import guard
