fix: enhance comment retrieval logic in getTaskComment function

- Updated the getTaskComment function to first attempt an exact match for comment IDs, followed by a prefix match for improved flexibility in retrieving comments with short IDs.
- This change ensures better handling of comment lookups, enhancing user experience when accessing task comments.
