Graceful end-of-session cleanup before the session is killed (Ctrl-C / closing the tab). Persists anything that would be lost (learnings worth keeping, a handoff doc if mid-task, in-flight decisions) and makes uncommitted git work safe locally. Fast and silent like an OS flushing buffers before power-off, then says "safe to shutdown". Invoke when done with a session: /shutdown, "done", "goodbye", "shutting down", "wrap up".
