opencrabs 0.3.30

//! Tests for the Qwen-style text-based tool-call extractor.
//!
//! Local GGUF/MLX backends (llama.cpp, MLX, LM Studio, Ollama) serving Qwen3
//! often emit tool calls as `<tool_call>{json}</tool_call>` or
//! `<function=name>...<parameter=key>val</parameter>...</function>` inside
//! `message.content` instead of the structured `tool_calls` field. The
//! extractor recovers them so they execute; these tests lock in the
//! contract — especially the edge cases (nested braces, open-ended tags,
//! prose mentions, field aliases).
