ci: Allow attaching claude-review label to PRs for automatic review

- If a pr is labeled with claude-review, review it immediately
- If a pr labeled with claude-review is updated, review it regardless
of the author
- If a pr is opened by a maintainer, review it and add the claude-review
label. If the claude-review label is later removed, the pr won't be
auto-reviewed anymore.
