Build Hokm card game: offline vs-AI + online social/gamification (mock backend)

- Pure-TS Hokm engine (deal, hakem, trump, tricks, scoring, Kot) + AI bots
- Persian-luxury RTL UI (Next 16 / React 19 / Tailwind v4 / Framer Motion / Zustand)
- Online platform behind OnlineService seam (mock now, .NET SignalR later):
  auth (phone OTP + email/Google), profiles, friends, private rooms with
  partner pick, ranked matchmaking, leaderboard, shop
- Gamification: ranks/leagues, coins, XP/levels, daily rewards, achievements
- i18n fa/en, PWA manifest, engine + gamification sims
