Initial commit: 酒桌派对 / 大话骰 multiplayer drinking-game hub

- server.py: zero-dependency stdlib backend (HTTP + WebSocket /ws), 大话骰 rule engine, server-driven bots
- live.html: real MVP frontend wired to the backend over WebSocket
- index.html/app.js/style.css: older static prototype
- deploy/: systemd unit + Nginx reverse proxy + Let's Encrypt setup.sh
- test_*.py: standalone HTTP / in-process test scripts
