New cg-bridge.el: a four-handed Bridge game (you are South, partnering
North against East and West) on the shared cg-game base.
* Auction: level/strain bids plus pass, double, and redouble, with the
three-pass end rule, pass-outs, doubling state, and declarer
determination (first of the side to name the strain).
* Play: follow-suit with the dummy exposed after the opening lead; the
declarer plays both hands. Trick resolution honours trump and no-trump.
* Scoring: classic rubber -- trick points below the line toward game;
overtricks, slam, insult, and undertrick penalties above; vulnerability
and the rubber bonus. Verified against known results.
* A small natural bidding AI (openings, NT, raises with a fit, simple
overcalls) that always terminates the auction, plus a greedy
card-play AI.
Wire cg-bridge into the chooser, the Makefile, and the README, and add
two ERT tests (scoring math and a dozen full AI-driven deals). The suite
is now 109/109 and every file byte-compiles cleanly.
