✨ Implement line wrapping for commit messages

Add textwrap dependency and use it to wrap commit message body

Modify format_commit_message function to wrap the message body at 78
characters, improving readability and adhering to Git best practices.
This change ensures that long commit messages are properly formatted
without manual intervention.
