Wire record_hyperopt_trial_duration, set_hyperopt_best_objective,
set_hyperopt_trial_best_loss, and set_hyperopt_elapsed into all three
optimizer paths (PSO sequential, PSO parallel, TPE). These metrics were
registered but never called during the optimization loop, causing
"Best Objective Over Time", "Trial Duration", and "Elapsed Time"
Grafana panels to show "No data".
