feat: Implement comprehensive Clerk ChunkLoadError recovery system

✨ Enhanced chunk error detection and automatic fallback to Supabase auth
- Enhanced isClerkChunkError with specific CDN pattern matching (joint-cheetah-86.clerk.accounts.dev)
- Added automatic Clerk disable when chunk loading fails
- Implemented graceful fallback to Supabase authentication without interruption
- Added user-friendly error messages and recovery UI
- Created multi-layered error handling across ErrorBoundary, ClerkProvider, and global handlers
- Added vite.config optimization for chunk loading with retry logic

🔧 Core improvements:
- setupChunkErrorProtection() now activates immediately in main.tsx
- Enhanced ClerkProvider with comprehensive error state handling
- App.tsx ErrorBoundary detects and handles Clerk-specific chunk errors
- Automatic sessionStorage flags for Clerk disable/skip functionality
- URL parameter support for noClerk=true debugging

🚀 User experience:
- Seamless transition from Clerk to Supabase when CDN fails
- No app crashes or white screens during authentication failures
- Automatic page refresh with fallback authentication system
- Clear error messages explaining recovery process

This resolves the ChunkLoadError: Loading chunk 344 failed from Clerk CDN
and ensures the app remains functional with Supabase authentication fallback.
