fix: prevent wrapper from detecting itself as remaining process

- Add PID and script name checks in post-test verification
- Avoid false positive detection of wrapper process as 'remaining'
- This prevents unnecessary cleanup calls that could cause hangs
- Root cause: wrapper was trying to clean up itself in verification phase
