fix: restore test files to master, fix lint, add react-dom devDep

- Restore ALL test files to master versions with only .ts import rewrites
  (removes leaked node:test/node:assert imports from PR2)
- Replace @typescript-eslint/ban-types with no-empty-object-type in
  inline disable comments (ban-types removed in v8)
- Fix invalid typeof comparison in rollupAdapter.ts
- Add eslintConfig.root: true to prevent parent config interference
- Add react-dom devDependency for storybook builder tests
- Regenerate package-lock.json from master base
