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.

+# v2-p2-async-bridge
+
+## Goal
+Bridge synchronous EventEmitter to asyncio so DiscussionEngine can run in a thread while WebSocket/SSE consumers receive events asynchronously.
+
+## Key files
+- `meeting_room/events.py` — add AsyncEventBridge class
+- `meeting_room/engine.py` — no changes (runs in thread as-is)
+
+## Decisions log
+- 2026-05-04: AsyncEventBridge + asyncio.to_thread() chosen over async engine rewrite. Minimizes changes, engine stays sync.
+
+## Open questions
+- [ ] None
+
+## Completed steps
+- [x] AsyncEventBridge class in events.py
+- [x] Thread-safe bridge with call_soon_threadsafe
+- [x] subscribe/unsubscribe consumer queues
+- [x] Drop policy on full queues
+- [x] Tests (10/10 passing)
+
+## Notes
+- events.py already has comment: "In Phase 2, an AsyncEventBridge will forward events to WebSocket clients"
+- Bridge subscribes to sync EventEmitter, puts events into asyncio.Queue
+- Consumers (WebSocket handlers, SSE handlers) read from the queue

+## Goal
+Create FastAPI application with REST API endpoints for session management and discussion control.

+
+## Decisions log
+- 2026-05-04: In-memory session store (dict). Persistent storage deferred.
+- 2026-05-04: REST routes under /api prefix, WebSocket/SSE on root

+## Open questions
+- [ ] None

+## Completed steps
+- [x] FastAPI app with lifespan handler
+- [x] Session + SessionStore models
+- [x] REST endpoints: POST /api/sessions, GET /api/sessions, GET /api/sessions/{id}, POST /api/sessions/{id}/start, POST /api/sessions/{id}/inject, GET /api/sessions/{id}/messages
+- [x] GET /api/roles, GET /api/providers
+- [x] Session start runs engine in asyncio.to_thread
+- [x] Tests (12 passing)
