## 🔧 Usage

### Simple Text Generation
```rust
let client = Client::from_env()?;
let response = client.generate_text("gpt-5", "Hello, world!").await?;
```

### Streaming Response
```rust
let mut stream = client.generate_text_stream("gpt-5", "Tell me a story").await?;
while let Some(chunk) = stream.next().await {
    print!("{}", chunk?.text);
}
```

### Structured Output
```rust
let schema = SchemaBuilder::object()
    .property("name", SchemaBuilder::string())
    .property("age", SchemaBuilder::number())
    .required(&["name", "age"])
    .build();

let response = client.create_structured_completion::<Person>(
    "gpt-5",
    "Extract: John, 30 years old",
    schema
).await?;
```

### YARA Validation
```rust
let validator = YaraValidator::new();
let result = validator.validate_rule(rule_content)?;
if result.is_valid {
    println!("Rule compiled successfully!");
}
```

## 🎯 Production Ready

The SDK is production-ready with:
