Notifications Change

[BenKothParadigm]

Describe the bug
After the latest update, our attempt to have claude only post one notification email instead of one per comment broke

To Reproduce

It used to just produce one email with all comments, same as if you manually did a "start a review" in github and added a bunch of comments. After the last update we are getting 1 email per comment.

Expected behavior
I expect claude to produce one email with all comments in it instead of an email per comment
