New tavolo-briscola distribution implementing briscola on the platform:
- pure rules (state.py, engine.py): 3-card deals, a face-up trump that
is the last card drawn, trump-first trick resolution (A > 3 > K > H >
J > 7 > 6 > 5 > 4 > 2), 120 points per deal, 60-60 patta re-deals, a
configurable target score (default 61), deal-end acknowledgements and
turn auto-play;
- BriscolaEngine (briscola, 2 players) and BriscolaQuattroEngine
(briscola_a_quattro, 4 players in fixed partnerships) adapters;
- registered in tavolo-app, packaged in the Docker image, documented.
Platform fixes surfaced by a two-player lobby:
- the websocket state and snapshot payloads now carry seats_open (they
were only in the REST lobby payload), so lobbies with player counts
other than four render correctly; seats_open is clamped at zero;
- the web client logs unparseable server messages instead of silently
dropping them.
Web client: briscola table for both variants (stock, face-up trump,
trick, last-trick banner), deal summary modal and game-over overlay.
Tests: tavolo-briscola rules/adapter suites, app integration tests
(lobby, websocket play, turn timeout, deal-end acks, persistence), a
platform seats_open test and frontend model parsing tests.
