Adding mamba2/predictive_coding/regime_dropout/isv_temporal_route/
risk_budget to submit_forward_ops_main broke graph_forward replay
on Hopper (same graph structure issue). Moved to run_full_step
between graph_forward replay and aux ops — ungraphed but still
runs every step, enriching h_s2 before IQL/IQN/attention.
graph_forward keeps the working kernel set (cuBLAS + ISV + plan).
