fix: resolve eslint-plugin-react-hooks 7.0.1 linting errors

Fixed ref access violations introduced by upgrading to eslint-plugin-react-hooks 7.0.1:
- Moved ref updates to useEffect in click_outside_wrapper.tsx
- Added ESLint disable comments for Floating UI library usage which legitimately requires refs during render
- Refactored shadow_root.tsx to use state with queueMicrotask to avoid cascading renders
