Root default

[andrej-jasso]

When trying to use the @navigable without Tabs as Root of the navigation I need a root implementation e.g.

/// The main listing view for the app, showing all the articles we downloaded.
@NavigationRoot struct Root: View {

    @ViewModel private var viewModel = RootViewModel()
    var content: () -> ArticlesList

    var body: some View {
        switch viewModel.destination {
        case .root:
            NavigationStack {
                content()
            }
        case .none:
            EmptyView()
        }
    }

}
