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(compiler): v0.4 + v0.5 — CLI modularity, diagnostic pipeline, test suite
v0.4 — CLI Modularity:
- Split monolithic main.rs (2,038 lines) into 8 command modules + slim dispatch (107 lines)
- Add 12 JS codegen tests (signals, derived, views, events, loops, match, enums, components, interpolation, springs, tree-shaking)
v0.5 — Diagnostic Quality + Analyzer Confidence:
- Add From<ParseError> for Diagnostic (E0001) in ds-diagnostic
- Add errors_as_diagnostics() to TypeChecker (E0100–E0110)
- Wire Elm-style diagnostics through dreamstack check and build commands
- Switch incremental compiler to parse_program_resilient() for multi-error collection
- Add 12 analyzer tests (chains, fan-out, diamond deps, empty programs, conditionals, handlers, views)
- Add 2 diagnostic conversion tests
Test suite: 97 → 123 tests (26 new, 0 failures)
