opencrabs 0.3.46

//! Tests for `looks_like_qwen_target` — the heuristic that decides whether
//! a custom provider gets `cache_control: {type: "ephemeral"}` markers
//! auto-applied to its outgoing requests.
//!
//! Detection trigger is OR-shaped: base_url match OR model match wins.
//! Match is strict (lowercase prefix on model, substring on URL) so that
//! adding markers to a non-matching backend stays at zero rate.
