gsxdsm 2add48c8b6 FN-6255: redirect tmpdir mkdtemp calls in tests

Keep test-created temp directories under the Fusion worker root.

- Redirect fs.mkdtemp and fs.promises.mkdtemp prefixes rooted at the OS temp dir into per-process worker sinks.
- Sweep stale redirect sinks and clean current-process sinks on exit.
- Add regression coverage for sync, async, realpath, nested, and Buffer prefix behavior.
- Remove the restored merger file-scope invariant test from quarantine.
