1. Refactored the way commit messages are composed and formatted.
2. Added support for displaying TTL information in the success message if a TTL (Time to Live) duration is provided.
3. Enqueued a delete operation when a TTL is set to automatically delete the shortlink after the specified time.
4. Handled errors gracefully using error checking.

These changes should enhance the readability and functionality of the code related to commit creation and TTL management.
