📝 Pull Request Title

Create .github/workflows directory

🛠️ Issue

• Closes #1

📖 Description

• This pull request adds the necessary directory structure for GitHub Actions to facilitate automation in the project. Additionally, an auto-assign workflow has been implemented to assign the maintainer as a reviewer automatically, and the author of the PR will be added as an assignee.

✅ Changes made

• Created a workflows subdirectory within .github.
• Added an empty YAML file named placeholder.yml to serve as a starting point for future workflows.
• Added an auto-assign.yml workflow file that automatically assigns the maintainer as a reviewer and will add the author of the pr as an assignee.

📜 Additional Notes

• This setup will allow for the easy addition of workflows later.
• The auto-assign workflow will trigger on opened and reopened pull requests, helping streamline the code review process.
• Further workflows can be added to the workflows directory as needed.
