Siavash Sameni	a52b011fb5	feat(relay): replace global Mutex<RoomManager> with DashMap sharding ... Eliminates the single-lock bottleneck for media forwarding. Before: all participants across all rooms competed for one Mutex. Now rooms are stored in DashMap (64 internal shards with per-shard RwLocks). Changes: - RoomManager.rooms: HashMap → DashMap<String, Room> - Per-room quality tracking (qualities, current_tier moved into Room) - Arc<Mutex<RoomManager>> → Arc<RoomManager> everywhere - 20 .lock().await sites removed across room.rs, main.rs, federation.rs, ws.rs - federation forward_to_peers: clone peer list, release lock, then send - ACL uses std::sync::Mutex (rarely accessed, non-async) Concurrency improvement: - Before: 100 rooms × 10 people = 1000 tasks → 1 Mutex - After: distributed across 64 DashMap shards, ~15 tasks per shard avg - Rooms are fully independent — room A never blocks room B 314 tests passing, 0 regressions.

Siavash Sameni	aa09275015	feat: WebSocket support in relay — browsers connect directly, no bridge ... Implements WS_RELAY_SPEC.md: relay handles both QUIC and WebSocket clients in shared rooms, eliminating the wzp-web bridge server. Room abstraction (room.rs): - New ParticipantSender enum: Quic(transport) | WebSocket(mpsc::Sender) - send_raw() sends PCM bytes to either transport type - join_ws() convenience method for WS clients - Forwarding loops handle mixed QUIC+WS rooms: QUIC→QUIC: send_media (trunked if enabled) QUIC→WS: send_raw payload bytes WS→QUIC: send_raw wraps in MediaPacket WS→WS: send_raw binary WebSocket handler (ws.rs): - GET /ws/{room} → WebSocket upgrade via axum - Auth: first msg {"type":"auth","token":"..."} → validates against FC - mpsc channel bridges room fan-out to WS binary frames - Session + presence lifecycle matches QUIC path - Optional static file serving via --static-dir (tower-http ServeDir) Config: --ws-port 8080, --static-dir ./static Proto: MediaHeader::default_pcm() for WS→QUIC wrapping 63 relay + 54 proto tests passing.
