Fix revision loop exit: change > 3 to >= 3, handle ESCALATE

Bug: Loop didn't exit after 3 revisions because:
1. revision_count > 3 was False when count = 3
2. ESCALATE status wasn't checked in should_continue

Fix:
- Change revision_count > 3 to >= 3
- Add check for critique_details.status == "ESCALATE"
