Fix critical issues breaking task execution cycle

- Fix branch name validation by hashing peer IDs using SHA256
- Fix Hive API claiming error by using correct 'task_number' parameter
- Improve console app display with 300% wider columns and adaptive width
- Add GitHub CLI integration to sandbox with token authentication
- Enhance system prompt with collaboration guidelines and help escalation
- Fix sandbox lifecycle to preserve work even if PR creation fails
