This hardens shared serve-mode instance cleanup so idle per-directory state does not linger longer than necessary.
It adds instance activity tracking and idle disposal, improves stale subprocess cleanup in the bash/process path, clears empty RPC/listener state, and makes related cleanup paths explicit in bootstrap, shutdown, and background resource handling.
