//! Shared runtime glue for Rust LLM backends.
//!
//! Two-type abstraction: [`LLMEngine`] (the engine trait an author implements)
//! and [`Worker`] (the runtime lifecycle owner), plus a [`run()`] helper called
//! from each backend's `main.rs`.
//!
//! Engines work directly with [`PreprocessedRequest`] and [`LLMEngineOutput`]
//! — the same types the rest of the Rust pipeline uses.
//!
//! See `CLAUDE.md` in this crate for the design contract.
