fix(perf-bottleneck): make find_slow_tests_pytest functional; unblock pytest collection

- find_slow_tests_pytest: actually run pytest with --durations and parse stdout
  instead of reading stale cache file. Now measures real test durations.
- test_pr_complexity_scorer.py: wrap module-level sys.exit() in
  if __name__ == "__main__" guard. This was crashing pytest collection
  entirely, making the repo un-testable and masking all other performance
  analysis.

Both issues were blocking the Performance Bottleneck Finder (#171) from
working. The script now successfully runs pytest, collects duration data,
and produces accurate reports.

Closes #171
