docs: add cross-node code synchronization and complete workflow

- Add Step 15: Cross-Node Code Synchronization
- Automatically pull latest changes on aitbc after git push on aitbc1
- Handle local changes with automatic stashing
- Detect blockchain code changes and restart services as needed
- Verify both nodes are running same version after sync
- Add Step 16: Complete Workflow Execution
- Provide end-to-end automated workflow execution
- Include interactive confirmation and comprehensive summary
- Cover all 16 steps for complete multi-node setup

This ensures both nodes stay synchronized with the latest code changes
and provides a complete automated workflow for multi-node deployment.
