Live-fire bug from the demo: collecting a re-roll answer deleted the
state file, so --update could not find the still-running server and the
next hand had nowhere to land. Cleanup is now terminal-only: a re-roll
consumes just the answer file and leaves the server state for --update;
any other choice cleans up fully as before.
