Rewrite README with usage guide, deployment instructions, and protocol
docs. Update CLAUDE.md to reflect gomoku-only architecture. Add English
doc comments to all key server Go files, replacing Chinese comments.
Create docs/system-architecture.md (state machine, protocol, database
schema) and docs/deployment-guide.md (local dev, Docker, production
nginx, resource requirements).
Update Dockerfile to Go 1.22 with repo-root build context to include
web client. Update docker-compose to match.
Add server-side gomoku (five-in-a-row) as game type 9 with 15x15 board,
2-player rooms, move validation, win detection in 4 directions, and
draw detection. Includes channel-based turn sync with mutex-protected
board access.
Add vanilla JS web client served as static files from the Go server:
WebSocket connection with base64 packet encoding, state machine
navigation, Canvas-based board renderer with gradient stones, hover
ghost, last-move highlight, and game-over overlay.
Import source files from ratel-online organization repos into monorepo
structure for gomoku game development. Update README with project
structure and credits for original authors.
