Currently review mode only triggers when a pull request is opened, synced, or reopened:

It would be great if allowed actions were expanded to more natural assignment:

• labeled
• review_requested

review_requested is maybe a bit more questionable since it requires a user, but could work similar to assigneee_triggerr.

However the actions already support label_trigger but it just gets bypassed with the early check as far as I can tell.

The use case is to assign only certain reviews for claude and only do it when the PR is ready. We can achieve that through a PR comment, but label is more natural and has the advantage of being trackable and filterable.
