🧹 Cleanup Summary:
- Fixed 83 oxlint warnings across 50+ files
- Removed unused imports, variables, and functions
- Maintained all functional code and error handling

📝 Key Changes:
- Cleaned unused React hooks (useState, useEffect, useClashInfo)
- Removed unused Material-UI imports (useTheme, styled components)
- Deleted unused interfaces and type definitions
- Fixed spread operator usage and boolean casting
- Simplified catch parameters where appropriate

🎯 Files Modified:
- React components: home.tsx, settings, profiles, etc.
- Custom hooks: use-*.ts files
- Utility functions and type definitions
- Configuration files

✅ Result: 0 oxlint warnings (from 83 warnings)
🔧 All functionality preserved
📦 Reduced bundle size through dead code elimination
