Add default label to all new issues

[JoannaaKL]

Summary

Add new workflow to automatically add a label for the AI Labeler workflow.

Why

Most of issues in this repo are created without labels. AI Labeler is only triggered if an issue labels match expected label.

Pull request overview

This PR adds automation to label all newly opened or reopened issues with "request ai review" to ensure the AI Labeler workflow can process them. The change addresses the problem where issues created without labels don't trigger AI assessment.

Changes:

• New workflow file to automatically add "request ai review" label to all opened/reopened issues
• Updated AI assessment workflow to trigger on the "request ai review" label instead of checking for unlabeled issues
• Minor formatting changes to use double quotes consistently

• The condition still checks for unlabeled issues on 'opened' events, but the new issue-labeler.yml workflow will add 'request ai review' label immediately on opened issues. This creates a race condition where the AI assessment may not run if the label is added before this workflow checks. The condition should be updated to trigger when labeled with 'request ai review' or remove the unlabeled check entirely since all new issues will now have the label.
