Research direction

Start with the Android-specific PackageReference entries in the shown JKC.csproj and the reported R8 output for androidx/lifecycle/ViewModelKt.class. Reproduce the net8.0-android34.0 build and trace which package references produce obj\Debug\net8.0-android34.0\lp\137 and lp\173; done means the project builds without the duplicate-class error.
