refactor: enhance reply comment functionality with improved error handling and response structure

- Simplified error handling in handleReplyComment to check for both comment_id and user_id simultaneously.
- Updated response message to include both Comment ID and User ID upon successful reply.
- Modified ReplyCommentArgs struct to make comment_id and user_id optional.
- Renamed MCP tool for replying to comments for clarity.
