+         references wwwroot assets under lib/ but the NuGet package only ships them
+         under staticwebassets/. Copy the files so the WinUI resource system finds them.
+         Only runs for Debug Windows builds (DevFlow is excluded from Release via
+         conditional PackageReference). Source-existence guards make this a no-op when

     <!-- The SDK registers the copilot CLI as ContentWithTargetPath but doesn't set
          PublishFolderType, so MAUI skips it when building the .app bundle.
          Re-register with PublishFolderType=Assembly so it lands in MonoBundle
