Replace the hand-rolled betting rules, side pots, showdown and hand
evaluator with the published @pokertools/engine and @pokertools/evaluator
libraries (MIT, pinned to 2.1.0).
- server/hand.js now wraps a PokerEngine per hand: it maps seats,
mirrors stacks, staggers the all-in runout, and pays host-chosen
winners on cash-only tables.
- server/cards.js and server/ai.js use the library evaluator.
- Out-of-turn folds go through the engine's stand; all-in hands stay
live when the player leaves; uncalled bets return to a leaver.
- The engine refuses some check-able folds that would leave a side pot
without eligible players; those now return a message (or check for
a leaving player) instead of crashing.
- BB must be greater than SB (engine requirement); Node >= 24.
- Tests rig cards via engine snapshots and cover the new edge cases.
