feat(core,rendering)!: add cleanup component support, refactor render pipeline

Introduce ICleanupComponent and cleanup archetype logic in ECS. Refactor component versioning to uint. Update IResourceDatabase to use map/unmap pattern. Decouple per-frame render requests from RenderSystem via IRenderPayload. Update render pipeline and extraction system to new API.

BREAKING CHANGE: Entity destruction and render pipeline APIs have changed. IResourceDatabase.MapResource signature is updated; all callers must use map/memcpy/unmap. RenderSystem no longer manages per-frame render requests directly.
