Create Flow.Launcher.Avalonia project as foundation for migrating from WPF to Avalonia UI framework. Key components: - MainWindow with query box and results list (matching WPF layout) - ViewModels: MainViewModel, ResultsViewModel, ResultViewModel - Themes/Base.axaml with converted styles from WPF - FluentAvaloniaUI for Windows 11 styling - References existing Core/Infrastructure/Plugin projects The project builds and runs alongside the existing WPF application. This is Phase 1 of the incremental migration approach.
