🎯 Zero Dependencies Achieved:
- Remove lucide-leptos from workspace dependencies
- Replace all conditional compilation with inline SVG icons
- Update examples to use inline SVG instead of external icon library
- Add examples to workspace for proper build integration

🔧 Technical Changes:
- Remove lucide-leptos from root Cargo.toml workspace dependencies
- Update examples Cargo.toml to remove lucide-leptos references
- Replace all conditional #[cfg(feature = "lucide-leptos")] with inline SVG
- Update button, alert, and card examples with proper SVG icons
- Update lazy_loading.rs to reference inline-svg instead of lucide-leptos
- Update scripts to reflect resolved compatibility issue

✅ Benefits:
- Zero external icon library dependencies
- Better performance with inline SVG
- Full compatibility with Leptos v0.8
- Consistent approach across all components and examples
- No version conflicts or compatibility issues

📦 Status:
- Examples build successfully with only warnings (no errors)
- All lucide-leptos references removed from source code
- Ready for production use with zero dependencies
