Add Kaiser, Crazy 8s and Wizard
Three more card games, engine to screen. Kaiser: 32-card prairie trick-taking with bidding, the five of hearts worth five and the three of spades costing three. Bidding is capped at ten because ten is all a hand can be worth, and a losing score gives the game a floor — without one a table that keeps bidding and going down never reaches a result. Crazy 8s: eights are wild and name the suit in force, which is why the table states that suit in words rather than leaving it to be read off the pile. Blocked rounds are scored rather than hanging. Wizard: the 60-card deck, one more card dealt each round until the pack runs out, bid your tricks exactly. The shared card model gains WIZARD and JESTER ranks, so every ordinary deck now builds from Rank.standard rather than walking the whole enum. Also fixes a lobby bug this would have hit: hosting seated the catalogue minimum rather than the table the host had just set up, so a six-handed game would have been rejected by its own rules engine. 164 engine tests pass locally.
