ai: Restart for the desktop assistant and local chat

A Restart button sits before Stop on a running app that has a restart
control. The assistant uses assistant.sh restart. llamachat has none,
and its --quit answers before the app has exited, so a --daemon sent
straight after finds an instance still running and does nothing: the
restart quits, waits for --ping to fail (5s at most), then starts it.
