feat(rendering): prove packed dispatcher output parity

Browse source 
Build a compare-only dispatcher classifier from RenderFrameView and compare complete opaque, alpha, selection, clip, light, texture, transform, and draw payloads against the accepted path. Preserve retail's stable equal-CYpt ordering with explicit draw-local submission ordinals so material-group history cannot affect alpha ties.
