Changed FyneApp.toml to reference VT_Icon.ico instead of VT_Icon.png.
Windows requires ICO format for proper application icon display in the taskbar and window title bar. PNG icons don't work correctly on Windows.
To apply this fix on Windows, rebuild with:
fyne package -os windows -icon assets/logo/VT_Icon.ico
- Update LoadAppIcon() to search for PNG first (better Linux support)
- Add FyneApp.toml for icon metadata and Windows embedding
- Create VideoTools.desktop for Linux application launcher integration
- Change default window size from 1200x700 to 800x600
- Icon now appears in taskbar, app switcher, and Windows title bar
