- Set ProtectSystem=false to allow color generation scripts to write files
- Fix MaterialThemeLoader to properly detect file changes with onFileChanged
- Add switchwall-wrapper.sh to source environment variables dynamically
- Fix light/dark mode buttons to use Process with current wallpaper
- Add --choose flag to switchwall.sh for wallpaper selection dialog
