feat: WebRTC transport — peer-to-peer data channels with auto-fallback
Relay:
- /signal/{channel} path for SDP/ICE exchange via WebSocket
- handle_signaling broadcasts text messages between signaling peers
- signaling_tx broadcast channel in ChannelState
- 46 ds-stream tests (+2 signaling path tests)
JS Runtime:
- _initWebRTC(signalingUrl, streamUrl, mode) with RTCPeerConnection
- Unordered DataChannel (ordered:false, maxRetransmits:0) for low latency
- Auto-fallback: WebSocket starts immediately, WebRTC upgrades in ≤5s
- Data channel override of _streamSend for transparent binary protocol
Parser/AST:
- StreamTransport enum (WebSocket, WebRTC)
- transport field in StreamDecl
- Parses: stream x on url { mode: signal, transport: webrtc }
Codegen:
- WebRTC: emits DS._initWebRTC(sigUrl, streamUrl, mode)
- WebSocket: emits DS._initStream(url, mode) (unchanged)

feat(relay): multi-source routing — /source/{name} and /stream/{name}
- ChannelState: per-channel broadcast, input mpsc, cache
- RelayState: HashMap<String, Arc<RwLock<ChannelState>>>
- parse_path: /source/{n}, /stream/{n}, legacy / fallback
- Per-channel stats logging with channel name prefix
- Backward compatible: plain /source and /stream use 'default' channel
- 44 ds-stream tests, 95 total workspace (0 failures)

feat(ds-stream): RLE compression, input events, keyframe caching
- protocol.rs: TouchEvent, GamepadAxisEvent, GamepadButtonEvent, ResizeEvent
with encode/decode and roundtrip tests
- codec.rs: rle_encode/rle_decode for delta frame compression (333x on
unchanged frames), signal_sync_frame/signal_diff_frame builders,
touch/gamepad/stream_end convenience builders
- relay.rs: StateCache for late-joining receivers (keyframe + signal sync +
accumulated diffs), periodic keepalive pings, stats logging every 30s,
diff accumulator with cap at 1000
- BITSTREAM_INTEGRATION.md: compiler integration spec for another agent
- Tests: 17 → 38 (all passing)

feat: universal bitstream streaming — any input → any output
New crate: engine/ds-stream/
- Binary protocol: 16-byte header, typed frame/input enums
- Frame types: Pixels, Delta, Audio, Signal, Neural (0x01-0x43)
- Input types: Pointer, Key, Scroll, Gamepad, MIDI, BCI (0x01-0x90)
- WebSocket relay server (tokio + tungstenite)
- Source → receivers: frame broadcast
- Receivers → source: input routing
- Codec: encode/decode, XOR delta compression, RLE, convenience builders
- 17 unit tests, all passing
Streaming modes (stream-source.html):
1. Pixel mode: raw RGBA framebuffer (~28 MB/s)
2. Delta mode: XOR + RLE compression (~1-9 MB/s, 70-95% savings)
3. Signal mode: compact JSON signal diffs (~2 KB/s, 12000x reduction)
4. Neural mode: procedural SDF pixel generator (concept demo)
5. Audio channel: spring velocity→frequency synthesis
6. Multi-receiver: broadcast to all connected clients
Thin receiver client (stream-receiver.html, ~300 lines):
- Zero framework, zero build step
- Renders any incoming bitstream mode
- Local signal-diff renderer for signal mode
- AudioContext playback for audio frames
- Full input capture: click/drag, keyboard, scroll
- Per-channel bitstream bus visualization
