详细描述

Caller-owned transactional backup of one Renderable3D renderer before Pcg LOD replacement.

The snapshot retains Graphics-owned resource pointers already held by the renderer. The owning Graphics instance and those resources must outlive this backup. Capture and restore are main/render-thread only, do not invoke callbacks, and validate the entity id plus generation before publication.
