PR Summary

This pull request includes the following changes:

• Refactored the Python source code by moving main.py into a new src/ directory.
• Removed the setup.py and __init__.py files, indicating the project is no longer intended to be distributed as a Python package.
• Updated the GitHub Actions workflow to correctly execute the main.py script from its new location (./src/main.py).
• Removed a redundant print(summary) statement from src/main.py, as the summary is already posted as a comment.
