gsxdsm 80fbcdd5a3 FN-6396: harden test worker temp cleanup ...

Prevent stale Fusion test worker roots from leaking across merge-gate runs.

- Add per-run tokens to worker-root owner markers and pruning checks.
- Remove self-minted fallback worker roots during Vitest exit cleanup.
- Cover stale pid reuse, markerless redir roots, and SIGKILL-style orphan pruning with regression tests.
