Add a test covering mcp-stdio:<pid>-<start_epoch> liveness checks so PID reuse cannot incorrectly preserve or release another process's claim.
Goal:
- validate sweeper behavior against PID recycling edge cases
Scope:
- test both pid match and start-epoch match requirements
- verify stale claims release correctly
- verify unrelated reused PIDs do not satisfy liveness
