- Deleted MainWindow.xaml.cs, which contained the WPF implementation of the main window.
- Updated Program.cs to remove Windows Forms initialization and support only Avalonia UI.
- Removed Windows Forms specific code from ViewModelBase, including control marshalling logic.
Refactored image creation APIs to use byte[] for logo data instead of System.Drawing.Image, enabling cross-platform support. Wrapped all GDI+/Windows-specific code in #if WINDOWS and updated project files to conditionally include Windows-only dependencies. Defaulted to ImageSharp on non-Windows, and updated UI and settings to reflect platform capabilities. Application now builds and runs on Linux/macOS with Avalonia and ImageSharp, while retaining full Windows functionality.
