// AppComposition.Initialize() builds the MEF host out of ILSpyX + ILSpy + any *.Plugin.dll
// siblings. TestApp.OnFrameworkInitializationCompleted invokes it during harness startup; if
// composition fails (missing export, duplicate Shared, broken import), AppComposition.Current
// throws InvalidOperationException, and every downstream test that does GetExport<T> hits a
// confusing failure further down the stack. This test catches the regression at the source.
