Describe the bug

There is logic in ApplicationExecutor for setting parent information onto child resources. However, it's only supported when the parent is a container:

aspire/src/Aspire.Hosting/Dcp/ApplicationExecutor.cs

Lines 195 to 209 in 3a35141

	private static ILookup<IResource?, IResourceWithParent> GetParentChildLookup(DistributedApplicationModel model)
	{
	static IResource? SelectParentContainerResource(IResource resource) => resource switch
	{
	IResourceWithParent rp => SelectParentContainerResource(rp.Parent),
	IResource r when r.IsContainer() => r,
	_ => null
	};
	// parent -> children lookup
	return model.Resources.OfType<IResourceWithParent>()
	.Select(x => (Child: x, Root: SelectParentContainerResource(x.Parent)))
	.Where(x => x.Root is not null)
	.ToLookup(x => x.Root, x => x.Child);
	}

Expected Behavior

IResourceWithParent should work well for containers, projects and executables.
