- Removed unnecessary duplicate prevention logic since we traverse linearly up the chain
- Removed visited_ids set as infinite loops are not possible in a linear chain
- Simplified while loop condition to just check current_comment_id
- Loop naturally terminates when replyTo is null (root comment reached)
