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
