- **Chain Listing**: View chains hosted on specific nodes
- **Node Configuration**: Add, remove, and manage node configurations
- **Real-time Monitoring**: Live node performance monitoring
- **Connectivity Testing**: Node connectivity and health checks

#### **4. Configuration Management**
- **Multi-Node Support**: Configuration for multiple AITBC nodes
- **Default Configuration**: Pre-configured with local and production nodes
- **Flexible Settings**: Timeout, retry, and connection management

### **📊 New CLI Commands Available**

#### **Node Management Commands**
```bash
aitbc node info <node_id>              # Get detailed node information
aitbc node chains [--show-private]     # List chains on all nodes
aitbc node list [--format=table]       # List configured nodes
aitbc node add <node_id> <endpoint>    # Add new node to configuration
aitbc node remove <node_id> [--force]  # Remove node from configuration
aitbc node monitor <node_id> [--realtime] # Monitor node activity
aitbc node test <node_id>              # Test node connectivity
```

#### **Enhanced Chain Commands**
```bash
aitbc chain list                       # Now shows live chains from nodes
aitbc chain info <chain_id>            # Real-time chain information
aitbc chain create <config_file>       # Create chain on real node
aitbc chain delete <chain_id>          # Delete chain from node
aitbc chain backup <chain_id>          # Backup chain from node
aitbc chain restore <backup_file>      # Restore chain to node
```
