The function re-ran 15+ kernels (expected_q, q_mean_center, q_anchoring, risk_budget, branch_confidence, epistemic_gate, temporal_consistency, branch_independence, q_attention, graph_message_pass, q_denoise) outside the graph every step — duplicating work the graph already did. Now: q_out_buf is populated by graph replay (populate_q_out in aux_child). reduce_current_q_stats just runs q_stats_kernel (1 kernel) + DtoH sync. Runs every step since cost is now ~1ms, not ~4s.
