/**
 * Controls whether to render the default scene at renderPriority=1.
 *
 * This component runs at renderPriority=1 and decides whether to render the main scene.
 * It skips rendering when:
 * - renderMode is 'postprocess' or 'pathtracer' (these have their own render loops)
 * - boundCameraKey is not null (virtual camera preview takes over)
 *
 * This allows GizmoHelper and other HUD components to use renderPriority=2
 * without automatically triggering a main scene render.
