refactor(pathfinder): address review feedback on test info logging

- Hardwire log filename with `pathfinder` prefix and `.txt` extension
- Retain strictness suffix so both CI runs produce separate logs
- Add `pytest_configure` to clean up stale log for the current
  strictness level (not all levels, preserving the other run's log)
- Add line count echo to `run-tests` for quick CI log grep
- Add `.gitignore` entry for the new `.txt` log files
- Update artifact upload paths in both workflow files
- Align default strictness fallback with `test_load_nvidia_dynamic_lib`
