OpenAPI client code generation.

Trait-based design allows multiple implementations per language/framework.

Extensibility

Users can register custom generators via [register()]:

use normalize_openapi::{OpenApiClientGenerator, register};
use serde_json::Value;

struct MyGenerator;

impl OpenApiClientGenerator for MyGenerator {
    fn language(&self) -> &'static str { "mylang" }
    fn variant(&self) -> &'static str { "myvariant" }
    fn generate(&self, spec: &Value) -> String { /* ... */ }
}

// Register before first use
register(&MyGenerator);
