ai: drop local chat

local-chat (llamachat) is archived and uninstalled, superseded by
desktop-assistant, so its row could only ever read stopped and its
buttons called a command that no longer exists. Also folds the control
comment that described llamachat's restart dance down to one line.

-Restart shows only while an app is running. llamachat's `--quit` answers
-before the app has exited, so a `--daemon` sent straight after finds it still
-running and does nothing; hence the wait.
+Restart shows only while an app is running.
 
 Each runs detached, so no exit code comes back; the next poll shows whether it
 worked. `assistant.sh status` fails when the daemon is down.
