       CsWinRT best-practice defaults for WinUI projects.

       Modeled on OSClient's UES.Common.CSharp.SDK.props
       (microsoft.visualstudio.com/OS — Build/MSBuild/UES.Common.CSharp.SDK.props),
       trimmed to the settings that make sense for a pure WinAppSDK repo
       (no UWP, no OS XAML mixing, no AOT-merged WinRT components).

       Gated on UseWinUI=true so analyzers/source-generators/etc that don't
       reference WinAppSDK keep their default behavior.
