Summary

Rebased on main (6.19.2). The source fix in this PR (import type * as React in 49 files) is removed, because #130 and #131 fixed the same problem on main with named type imports. This PR now contains only the regression guard for #126.

pnpm lint:dist            (run after pnpm build)
  remove `export as namespace React;` from @types/react in memory
  type-check each dist/**/*.d.ts with skipLibCheck: false
  fail if dist is empty, or if the global was not found in @types/react
  fail on a diagnostic in dist

libui's own tsc cannot find this class of error, because @types/react supplies the global React namespace.

Evidence

• Before: a bare React.ComponentProps put into dist/components/Checkbox/Checkbox.d.ts by hand:
  Found 1 error(s) in 1 of 204 declaration file(s). (exit code 1)
  After: a clean build of this branch:
  Checked 204 declaration file(s) without the global React namespace: no errors.
• pnpm lint and pnpm build pass. pnpm test: 41 files, 226 tests pass.

Merge Danger

Door: two-way

No published file changes. A revert removes the check only.

Blast Radius: CI

The test and release workflows now build and run lint:dist. A declaration that uses React without an import will stop the workflow. The commit type does not cause a release.

Closes #126
