Major changes:
- Eliminate ALL runtime NVRTC: c51_loss + mse_loss kernels converted to
precompiled cubins with runtime num_atoms/v_min/v_max/branch params
- Fix evaluator SIGSEGV: rng_states/q_gaps sized for chunked batch (cn)
not n_windows; NULL pointer guard in action_select kernel
- Add trade_physics.cuh shared header for train/eval consistency
- Add equity circuit breaker (25% DD from peak) + margin-aware position cap
- Consolidate 46D→22D hyperopt search space, enable ensemble by default
- Fix trade counting: use exposure index not factored action
- Fix Calmar overflow: clamp to ±100 in kernel
- Softer CVaR penalty (cap 3.0 not 10.0) for undertrained models
- Fix win_rate display (ratio→percentage)
- Remove dead code (normalize_reward, calculate_completion_penalty)
- Add tracing subscriber to hyperopt test for visible metrics
- Per-chunk sync in evaluator for reliable error reporting
