feat: Complete deploy-rs integration with status monitoring

✅ Completed Tasks:
- Task 6: Successfully tested deploy-rs on all machines (grey-area, reverse-proxy, congenital-optimist)
- Task 7: Added deploy-rs status monitoring to lab tool

🔧 Infrastructure Improvements:
- Added sma user to local machine for consistent SSH access
- Created shared shell-aliases.nix module to eliminate conflicts
- Enhanced lab status command with deploy-rs deployment info
- Added generation tracking, build dates, and uptime monitoring

🚀 Deploy-rs Status:
- All 4 machines successfully tested with both dry-run and actual deployments
- Automatic rollback protection working correctly
- Health checks and magic rollback functioning properly
- Tailscale connectivity verified across all nodes

📊 New Status Features:
- lab status --deploy-rs: Shows deployment details
- lab status -v: Verbose SSH connection info
- lab status -vd: Combined verbose + deploy-rs info
- Real-time generation and system closure information

The hybrid deployment approach is now fully operational with modern safety features while maintaining legacy compatibility.
