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.

Inizia individuando nel repository l’elenco dei commenti delle pull request e i relativi punti di ingresso esistenti per il filtraggio Active/Resolved. Determina come sono rappresentate le reazioni ai commenti, quindi definisci il filtraggio dei commenti con reazioni selezionate; il lavoro è completato quando l’elenco dei commenti può filtrare in base alla presenza di una reazione senza interrompere gli stati esistenti.
