TASK 51 slice 4: camera-path hookup — CameraManager renders per-scene effect variants (one segmentation per raw frame on a latest-frame-drop worker, raw path untouched), VM declares/adopts variants per config; separable upsampling cuts Remove 46->3 ms, Blur 80->18 ms (Debug, 720p) (Unit: bg-effects hookup)
