M1: ядро правил дурака (чистый TypeScript, без движка)

Детерминированный конечный автомат: apply(state, action) -> {state, events}.
Весь набор правил из GAMEPLAY.md проверяется headless-тестами.

- карты: Suit/Rank/Card (флайвейт, 36 штук), колода
- GameState + клонирование и сериализация в JSON
- действия (attack/defend/take/pass) и события для слоя отображения
- раздача, выбор первого атакующего, лимиты подкидывания,
  взятие карт, добор, выбывание игроков, определение дурака
- 64 теста, strict typecheck
