Client: sends SignalMessage::Hangup(Normal) before closing in all modes
(send-tone, file mode, silence mode) so the relay knows the session ended.
Relay: downgrades "timed out" / "reset" / "closed" recv errors from
ERROR to INFO since these are normal disconnect scenarios.

T6 wiring: Trunking in relay hot path
- TrunkedForwarder wraps transport with TrunkBatcher
- run_participant uses 5ms flush timer when trunking enabled
- send_trunk/recv_trunk on QuinnTransport
- --trunking flag on relay config
- 2 new tests: forwarder batches, auto-flush on full
T7 wiring: Mini-frames in encoder/decoder
- MediaPacket::encode_compact/decode_compact with MiniFrameContext
- CallEncoder sends mini-headers for consecutive frames (full every 50th)
- CallDecoder auto-detects full vs mini on receive
- mini_frames_enabled in CallConfig (default true)
- 3 new tests: encode/decode sequence, periodic full, disabled mode
Noise suppression (nnnoiseless/RNNoise)
- NoiseSupressor in wzp-codec: pure Rust ML-based noise removal
- Processes 960-sample frames as two 480-sample halves
- Integrated in CallEncoder before silence detection
- noise_suppression in CallConfig (default true)
- 4 new tests: creation, processing, SNR improvement, passthrough
T1-S4: Adaptive playout delay
- AdaptivePlayoutDelay: EMA-based jitter tracking (NetEq-inspired)
- Computes target_delay from observed inter-arrival jitter
- JitterBuffer::new_adaptive() uses adaptive delay
- adaptive_jitter in CallConfig (default true)
- 5 new tests: stable, jitter increase, recovery, clamping, estimate

WZP-S-4: Room access control
- hash_room_name() in wzp-crypto: SHA-256("featherchat-group:"+name)[:16]
- CLI --room flag hashes before SNI, web bridge does the same
- RoomManager gains ACL: with_acl(), allow(), is_authorized()
- join() returns Result, rejects unauthorized fingerprints
WZP-S-5: Crypto handshake wired into all live paths
- CLI: perform_handshake() after connect, before any mode
- Relay: accept_handshake() after auth, before room join
- Web bridge: perform_handshake() after auth, before audio
- Relay generates ephemeral identity at startup
WZP-S-6: Web bridge featherChat auth
- --auth-url flag: browsers send {"type":"auth","token":"..."} as first WS msg
- Validates against featherChat, passes token to relay
- --cert/--key flags for production TLS (replaces self-signed)
WZP-S-7: wzp-proto standalone
- Cargo.toml uses explicit versions (no workspace inheritance)
- FC can use as git dependency
WZP-S-9: All 6 hardcoded assumptions resolved
- Auth, hashed rooms, mandatory handshake, real TLS certs,
profile negotiation, token validation
CLI also gains --room and --token flags.
179 tests passing across all crates.

Room-based SFU relay:
- Clients join named rooms (room name from QUIC SNI)
- Each participant's packets forwarded to all others (no mixing)
- Multiple rooms run concurrently on one relay
- Web bridge passes room name from URL path to relay
Push-to-talk (radio mode):
- Toggle "Radio mode" checkbox after connecting
- Hold PTT button or spacebar to transmit
- Release to mute mic (receive-only)
- Works on desktop (spacebar) and mobile (touch)
URL routing:
- /myroom → joins room "myroom"
- Room name input field as fallback
