CLAUDE: step-3 carve_combo case - pose DP + render chain in disjoint green-ctx carves, one thread

MAP v1 (B) at real-kernel level: pose scene_dp (K=2) in its carve while
render_dp flies in a disjoint carve. Gates: pose packed result + vector
bit-identical solo-vs-combo EVERY scene (cross-ctx numerical isolation),
render output tol-0 vs solo. Measured (pinned): pose 5.1->8.3 ms p50 with
render in ANY disjoint carve (+3.1 = DRAM/L2 contention, SM-invariant);
uncarved-pose fallback (A) worst at +4.3 (primary spreads into render SMs).
Render residual wait ~0 in all arrangements.
