* Add winui plugin from microsoft/win-dev-skills
Adds the Microsoft-maintained WinUI 3 development plugin as an external
plugin reference. This is a Microsoft-managed repository so it qualifies
for the external-plugin policy exception in CONTRIBUTING.md.
The plugin provides agents and skills for WinUI 3 app development:
new app scaffolding, framework migration (WPF, WinForms, Electron,
Tauri, Flutter to WinUI 3), MSIX packaging, code signing, UI
automation testing, and Windows App SDK guidance.
