//! Smoke test that makes a REAL call to Z.ai / 智谱.
//!
//! Ignored by default — it costs tokens and needs network + an API key. To run:
//!
//! ```bash
//! ZAI_API_KEY=<your-key> cargo test -p focus-providers --test zai_smoke -- --ignored --nocapture
//! ```
//!
//! It prompts the model in Chinese and asserts a non-empty response is streamed.
