// 트랙 C3 — DecalSystem 등록/해지. Awake/OnDestroy(컴포넌트당 1회 게이트)가
// 아니라 씬 편입/이탈 훅을 쓰는 이유는 AnimatorSystem.h 상단 주석 참고 — DDOL
// 오브젝트가 씬을 건널 때도 매번 다시 불려야 하기 때문이다. 실제 파괴 경로
// (Scene::FlushPendingDestroy·PrefabUtility::ApplyComponentDiff)도
// OnUninitializing(위 OnDestroy 브리지) 직전에 OnRemovingFromScene을 먼저
// 부르므로, 이 시스템에서 빠지는 시점이 항상 실 파괴보다 먼저다.
