feat(engine): establish calcpad-engine workspace with Epic 1 modules
Cherry-picked and integrated the best code from 105 parallel epic
branches into a clean workspace structure:
- calcpad-engine/: Core Rust crate with lexer, parser, AST,
interpreter, types, FFI (C ABI), pipeline, error handling,
span tracking, eval context (from epic/1-5 base)
- calcpad-engine/src/number.rs: Arbitrary precision arithmetic
via dashu crate, WASM-compatible, exact decimals (from epic/1-4)
- calcpad-engine/src/sheet_context.rs: SheetContext with dependency
graph, dirty tracking, circular detection, cheap clone (from epic/1-8)
- calcpad-wasm/: Thin WASM wrapper crate via wasm-bindgen,
delegates to calcpad-engine (from epic/1-6)
- Updated .gitignore for target/, node_modules/, build artifacts
- Fixed run-pipeline.sh for macOS compat and CalcPad phases
79 tests passing across workspace.
