<!-- Work around a packaging bug in Microsoft.Maui.DevFlow.Blazor where the PRI
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 package version changes or the upstream fix ships. -->

<!-- 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
