feat: Phase 2 — web server, REST API, WebSocket/SSE, UI [v0.2.0]

AsyncEventBridge bridges sync EventEmitter to asyncio consumers.
FastAPI app with session management, discussion control, roles/providers.
WebSocket for real-time events + inject, SSE for read-only streaming.
Minimal dark-theme HTML/JS UI. `meeting-room serve` CLI subcommand.
