Introduce the build-time compiler for constrained-JSX skins, rebased onto
current main as a clean, additive package. Provides:
- core pipeline: parse, compile, generate, JSX runtime, define-component
- transforms: import rewriting, replace/wrap, drop-unused locals/imports
- matchers + react lowering (add-prop, child-as-prop)
- styles className analyzer
- tailwind subsystem: design-system loader, decompose, evaluator,
deriveClassName, emitCss, tailwindPlugin (three targets)
Self-contained: the integration smoke test now reads a vendored skin
fixture instead of the skins package, so the compiler builds and tests
green independently. 158 tests pass.
Wiring: register the project reference (tsconfig), commitlint scope,
CI test-matrix entry, and lockfile entries (lightningcss, tailwindcss).
The skin migration that consumes this compiler is parked separately —
its token refactor conflicts with skin work that landed on main; see the
follow-up commit and .claude/plans/compiler-rebase-audit.md.
