tinyagents 0.1.1

//! Live steering test against the real OpenAI API.
//!
//! Skips gracefully (early return) when `OPENAI_API_KEY` is unset, so
//! `cargo test --features openai` stays green without credentials. Run it for
//! real with:
//!
//! ```text
//! cargo test --features openai --test live_steering -- --nocapture
//! ```
