feat: add Supervisor process manager for service management

- Add supervisord.conf with ComfyUI and orchestrator services
- Update Ansible playbook with supervisor installation tag
- Rewrite start-all.sh and stop-all.sh to use Supervisor
- Add status.sh script for checking service status
- Update arty.yml with supervisor commands and shortcuts
- Update CLAUDE.md with Supervisor documentation and troubleshooting
- Services now auto-restart on crashes with centralized logging

Benefits:
- Better process control than manual pkill/background jobs
- Auto-restart on service crashes
- Centralized log management in /workspace/logs/
- Web interface for monitoring (port 9001)
- Works perfectly in RunPod containers (no systemd needed)
