feat: Windows GUI development with egui - simple notepad example

- Fixed EguiBox Send+Sync trait bounds for thread safety
- Added missing Arc import for EguiBox implementation
- Simplified font setup in Windows notepad example
- Successfully built 4.5MB Windows GUI executable
- Nyash can now create native Windows desktop applications! 🎉
