Filter comments by reactions

GitHub has only the Active and Resolved states for comment threads. This can be painful for complex PRs with large numbers of comments, where it would be more productive to track the status of thread in a finer grained way.

I sometimes use emoji reactions to simulate these states, e.g. using 👀 on the original comment to indicate pending (I'm now working on the change that addresses the thread, I haven't pushed it yet), or 👍 to indicate addressed (I pushed a fix, but original reviewer should check, decide if they agree that the problem is resolved, then hit Resolve on the comment thread).

As part of working with comments "tagged" in these ways, it would be nice to be able to filter the comments list, by whether certain reactions are present on the comments or not.

まず、リポジトリ内でプルリクエストのコメント一覧と、既存のActive/Resolvedフィルタリングのエントリーポイントを見つけます。コメントのリアクションがどのように表現されているかを確認し、選択したリアクションを持つコメントのフィルタリングを定義します。既存の状態を妨げることなく、コメント一覧をリアクションの有無でフィルタリングできれば完了です。
