ea64617569
- Add scene container to AST, lexer, parser, analyzer, and codegen
- Add circle/rect/line as UI elements for physics body declaration
- Compile scene {} to canvas + async WASM init + Rapier2D PhysicsWorld
- Reactive gravity via DS.effect() — bodies wake on gravity change
- Mouse drag interaction with impulse-based body movement
- Compile-time hex color parsing for body colors
- Fix is_signal_ref matching numeric literals (700.value bug)
- Fix body variable uniqueness (next_node_id per body)
- Fix gravity signal detection (check AST Ident before emit_expr)
- Add physics.ds example with 5 bodies + 4 gravity control buttons
- Update DREAMSTACK.md and IMPLEMENTATION_PLAN.md with Phase 10-11
- 39 tests pass across all crates, 22KB output
