gsxdsm 4032a35a2f FN-6188: harden AI merge temp worktree cleanup

Improve AI merge temp worktree cleanup and add recovery coverage.

- audit AI merge clean-room cleanup success and failure paths, including stderr/code details
- sweep stale fusion-ai-merge temp directories from tmpdir() during self-healing with active-session safeguards
- document the native temp-dir sweep behavior and add merge cleanup/self-healing regression tests
