/noitubot now sends its own BotFather game, noitubot, so players can tell a
solo game from a /noitu room card. Both games share the Play handler and page.
A noitubot Play press skips the card lookup and always plays solo.
/noitu now posts the group play card that /noitupvp used to, and the solo
game against the bot moves to /noitubot. In a private chat /noitu points
the user to a group, or to /noitubot.
/noitutop ranks a group's players across all of its cards by wins, best
game and games played.
A one-time startup migration moves /stats history to the new names in
order: noitu to noitubot first, then noitupvp to noitu.
Serve the BotFather game noitu from the bot's HTTP server under
/games/noitu when GAME_BASE_URL is set. /noitu sends the game, Play
answers with a signed, expiring link, and the server validates every
word against the embedded noitu dictionary (CC BY-SA 4.0), runs the
bot opponent and turn timer, and reports the score with setGameScore.
Modules can now register game-short-name callbacks and HTTP routes.
