Minimal scene graph item that drives Qt Quick render frames on demand. In Qt 6.8+, QQuickWindow::update() alone may not trigger beforeRenderPassRecording when no QML items are dirty. By participating in the scene graph with ItemHasContents set, calling update() on this item properly marks the scene as dirty, guaranteeing a render frame will be produced and beforeRenderPassRecording will fire.
