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

feat: Phase 3+4 — Cassowary constraint solver + type system
Phase 3 — Constraint Layout:
- ds-layout crate: Gaussian elimination constraint solver
- eq, gte, lte, sum_eq, ratio constraints with strength priority
- get_rect() for resolving absolute (x,y,w,h) layouts
- 7 tests: simple eq, two-var eq, sums, rects, gte, ratio, 3-panel
Phase 4 — Type System:
- ds-types crate: Signal<T>, Derived<T>, Stream<T>, Spring<T>, View
- Effect types: Http, Storage, Time, Dom, Custom(name)
- Hindley-Milner type checker with signal-awareness
- Elm-inspired error messages (TYPE MISMATCH, UNHANDLED EFFECT, etc.)
- 11 tests: type display, reactive checks, mismatch errors, etc.
Total: 34 tests passing across 6 crates

feat: DreamStack compiler foundation — Phase 0/1
Complete compiler pipeline from .ds source to reactive browser apps:
- ds-parser: lexer (string interpolation, operators, keywords) + recursive
descent parser with operator precedence + full AST types
- ds-analyzer: signal graph extraction (source/derived classification),
topological sort for glitch-free propagation, DOM binding analysis
- ds-codegen: JavaScript emitter with embedded reactive runtime (~3KB
signal/derived/effect system) and dark-theme CSS design system
- ds-cli: build (compile to HTML+JS), dev (live server), check (analyze)
Verified working: source signals, derived signals, event handlers,
conditional rendering (when), 12 unit tests passing, 6.8KB output.
