Expand pull request action triggers for review mode

[ltamrazov]

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

claude-code-action/src/modes/review/index.ts

Line 42 in 15db2b3

const allowedActions = ["opened", "synchronize", "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.

it also needs ready_for_review

@ltamrazov @aulneau, great suggestions! In #421 we're moving towards not restricting event types and keep it completely user driven. This should help with this. Sorry for all the thrash with the modes, just want to give an ideal ux!

Hey folks, AFAIU we're still lacking mode detection for pull_request.labeled -- is it still in the plans?

Hi @ashwin-ant
Any progress on that?
