Project cleanup and testing improvements

[mmcky]

Summary

This PR addresses project structure and testing improvements based on a comprehensive review:

Changes Made

🗂️ Project Organization

• ✅ Keep current flat structure - Confirmed this is the correct pattern for GitHub Actions (not moving to src/ folder)
• ➕ Added comprehensive .gitignore - Prevents common Python/development artifacts from being committed

🧪 Testing Improvements

• 🔄 Updated CI to test Python 3.12 and 3.13 only - Modernized to current/supported Python versions
• 🐛 Fixed test failure - Corrected test_modules.py to call existing function extract_links_from_html instead of non-existent parse_html_file
• ✅ Verified tests pass - All tests now run successfully

📁 Files Changed

• .gitignore - New comprehensive ignore patterns for Python projects
• .github/workflows/ci.yml - Updated Python version matrix
• tests/test_modules.py - Fixed function call in test

Testing

• ✅ Local tests pass with python test_modules.py
• ✅ CI will now test on Python 3.12 and 3.13
• ✅ No breaking changes to action functionality

Review Notes

During the review, I confirmed:

• Current project structure is optimal for GitHub Actions
• Documentation is excellent and comprehensive
• Code quality follows good practices
• No major structural changes needed

This PR implements the minimal necessary improvements while maintaining the project's excellent existing organization.
