Pull request overview

This PR optimizes the Python CI workflow to run only when Delphi-related files change and improves coverage comment management by updating existing comments instead of creating new ones.

Key Changes:

• Added path filters to trigger the workflow only for changes to Delphi Python files, requirements, Dockerfile, or the workflow itself
• Modified coverage reporting to update existing comments instead of creating duplicates
