Add Phase 1 MVP: D&D text-adventure server

FastAPI + Postgres backend with fastapi-users auth, games/characters CRUD, and a WebSocket chat endpoint where an x.ai Grok DM narrates play, rolls dice, and maintains character sheets via tool calls. React + Tailwind frontend covers registration/login, game list and creation, participation-code join flow, character viewer, and a real-time chat session view. Docker Compose skeleton (Postgres + backend) included; Caddy/frontend container wiring is deferred to the deploy milestone. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
