```rust
pub struct AgentCoordinator { ... }
pub struct MessageBus { ... }
pub struct SharedMemory { ... }
pub struct Message { ... }
pub enum MessagePriority { ... }
pub enum MessagePayload { ... }
pub enum CoordinationError { ... }

## Example Usage

### Multi-Agent Coordination

```rust
let mut coordinator = AgentCoordinator::new();

let id1 = coordinator.register_agent(KaneruAgent::with_default_config());
let id2 = coordinator.register_agent(KaneruAgent::with_default_config());

// Broadcast to all agents
coordinator.broadcast(Message::new("update", "System status"));

// Shared memory
coordinator.shared_memory_mut().set("temp".to_string(), "25.0".to_string());

// Consensus voting
let proposal = coordinator.create_proposal("policy", "Adopt new policy?");
let result = coordinator.get_consensus(&proposal);
```

### State Persistence

```rust
let agent = KaneruAgent::with_default_config();

// Train agent...

// Save to file
agent.save_to_file(Path::new("agent.json")).unwrap();

// Load from file
let loaded = KaneruAgent::load_from_file(Path::new("agent.json")).unwrap();

// Checkpoint manager
let mut manager = CheckpointManager::new(Path::new("checkpoints"), 5)
    .with_interval(1000);

if manager.should_checkpoint(step) {
    manager.save_checkpoint(&agent, step).unwrap();
}
```
