//! Doubleword API extensions (`dwext`).
//!
//! Following NVIDIA's `nvext` pattern, all Doubleword-specific fields live under
//! a top-level `dwext` key. This preserves OpenAI API compatibility — any standard
//! client ignores unknown top-level keys, while Doubleword clients can opt in to
//! extended functionality.
