This branch does the following:

  1. Adds a per-rank JSONL metrics logger (src/professor/trainer_metrics.py)
  2. Exposes some additional DataLoader tuning knobs (--pin_memory, --persistent_workers, --prefetch_factor, --prof-metrics-*) in prof-trainer.

These changes help enable reproducible performance benchmarking/profiling work: without them, runs on main can't record step timing, DataLoader wait, or run configuration. Additionally, these metrics act as a lightweight way to gather information without invoking the full pytorch profiler.
