Protocol System Module

This module provides protocol definitions for agent implementations:

* `AgentProtocol` - Minimal protocol for agent implementations
* `RunnableAgentProtocol` - Extended protocol with run/start methods
* `AgentOSProtocol` - Agent OS integration protocol

# Example

```ignore theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
use praisonai::protocols::AgentProtocol;

struct MockAgent {
name: String,
}

impl AgentProtocol for MockAgent {
fn name(&self) -> &str { &self.name }
fn chat(&self, prompt: &str) -> String { "Response".to_string() }
}
```

## Import

```rust theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
use praisonai::protocols::*;
```
