Enum EvalResult 

pub enum EvalResult {
    Ok {
        value: String,
        js_type: String,
    },
    Thrown {
        kind: String,
        message: String,
    },
    Syntax {
        message: String,
    },
}

Result of Engine::eval_js. The Ok variant carries a JSON- serialized value (or empty for undefined/null); errors are distinguished by kind so the agent can react differently to a thrown exception vs. a SyntaxError vs. a binding/IO failure.
