feat(apollo-wind): enable React Compiler

[SreedharAvvari]

Summary

• Add babel-plugin-react-compiler to the Rslib build pipeline for @uipath/apollo-wind
• Fix 2 ref mutation violations in MetadataForm and FormDesigner that would cause the compiler to bail out
• Enable full compilation mode — 69/70 React components (98.6%) are now compiler-optimized
• Add React Compiler to Storybook's Vite config so react-scan profiling reflects real compiled performance

Changes

Commit	What
add react compiler in annotation mode	Install deps, configure pluginBabel with compilationMode: 'annotation'
move ref assignments to useEffect	Fix valuesRef.current and contextRef.current render-phase mutations in MetadataForm
convert mutable useMemo to useRef	Fix currentTypeRef mutable object pattern in FormDesigner
enable react compiler for all components	Switch from annotation mode to full compilation
enable react compiler in storybook	Add @vitejs/plugin-react with compiler to Storybook's Vite config

Verification

• 920/920 tests pass (zero failures)
• 69/70 React components compiled (1 example file skipped due to JSX in default params)
• Build: 91 files, 176.1 KB gzipped ESM
• Lint: 259 files checked, zero issues
• Zero "use no memo" opt-outs needed

Pull request overview

Enables the React Compiler for @uipath/apollo-wind by wiring babel-plugin-react-compiler into the library (Rslib/Rsbuild) build pipeline and Storybook’s Vite pipeline, plus refactorings intended to remove render-phase mutations that cause compiler bailouts.

Changes:

• Add React Compiler Babel plugin to @uipath/apollo-wind Rslib build via @rsbuild/plugin-babel.
• Refactor MetadataForm and FormDesigner to avoid render-phase ref mutations (compiler compatibility).
• Enable React Compiler in Storybook Vite config for more representative react-scan profiling.
