RematchOffers keeps an offer open for ten minutes after a game nobody
left. A request goes to the opponent; when both have asked the next game
of the series starts with the other player moving first. Requests end on
no, withdrawal, a minute without answer, going offline or looking for
another game. The bot accepts at once.
new_bot_game starts a game against the bot at the chosen level and ends the
search for an opponent. BotPlayer works out the bot's moves on its own thread
pool and plays them on the game loop after the previous move's animation and a
thinking time. Bot games keep their settings across restarts.
The Quarkus project moves to apps/backend and the Express sources go.
The image is built from the repo root as before, with Temurin 25, and
runs as a non-root user on port 6000. Compose passes the database as a
JDBC URL with the same MANCALA_DB_PASSWORD.
