fix: Improve CCExtractor binary path resolution

- Fix path resolution to check bundled executable first, then fall back
  to system PATH (was incorrectly detecting non-executable files)
- Add debug logging to extraction process for troubleshooting
- Log CCExtractor stdout/stderr output for visibility
