M2: бот и headless-прогон матчей

- PlayerView: проекция состояния, в которой боту видно только то,
  что видно живому игроку (своя рука, стол, размеры чужих рук, счётчики)
- BasicBot: политика из GAMEPLAY.md, полностью детерминированная
- Match: обёртка с состоянием и подпиской на события (её же возьмёт UI)
- runMatch: прогон матча без движка и без таймеров
- soak-тесты: 3500 полных матчей (боты и случайные легальные ходы,
  2-4 игрока), инварианты состояния проверяются после каждого действия
- npm run stats:bot — распределение исходов самоигры
