fix: ensure agents respond to comments on in_review tasks

Root cause: when someone commented on an in_review task, the heartbeat
wakeup was triggered but the agent couldn't re-checkout the task because
expectedStatuses only included todo/backlog/blocked. The in_review status
was never handled in the checkout flow or the heartbeat procedure.

Changes:
- Add wakeCommentId to issue_commented and issue_reopened_via_comment
  context snapshots (consistent with issue_comment_mentioned)
- Add in_review to checkout expectedStatuses in heartbeat skill
- Update Step 3 fallback query to include in_review status
- Update Step 4 to prioritize in_review tasks when woken by comment
- Add explicit issue_commented wake reason handling in Step 4
