Struct Request 

pub struct Request<'a> {
    pub model: &'a str,
    pub max_tokens: u32,
    pub system: &'a [SystemBlock],
    pub messages: &'a [UserMessage],
}

One LLM call’s worth of input. Mirrors the Anthropic Messages request shape because it’s the most expressive of the three providers we’ll support; OpenAI and Ollama adapters convert to their native shapes inside their own complete impls.
