- Restructured app directory with [locale] routing (/ro, /en)
- Created comprehensive translation files for both languages
- Fixed Next.js 15 async params compatibility in layout components
- Updated all components to use proper i18n hooks and translations
- Configured middleware for locale routing and fallbacks
- Fixed FloatingChat component translation array handling
- Restored complete home page with internationalized content
- Fixed Material-UI Slide component prop error (mountOnExit → unmountOnExit)
