🌟 Summary

Automated "main" branch merger into open PRs action removed 🚫🔀

📊 Key Changes

• Deleted the GitHub action workflow file that automatically merged changes from the "main" branch into all open Pull Requests (PRs).

🎯 Purpose & Impact

• Simplification of Workflow: Removing this action may simplify the development process, reducing automatic merges that could interrupt work in progress.
• Increased Manual Control: Developers will now have more control over when and how to integrate changes from the "main" branch into their open PRs, potentially improving code quality and reducing merge conflicts.
• Potential for More Attention to Detail: Without automatic merges, contributors might pay more attention to integrating updates from the main branch, leading to more thoughtful and deliberate conflict resolution and code integration.
