//! Google Gemini function-declaration adapter.
//!
//! Shape: {"name":..., "description":..., "parameters":...}
//! Gemini uses the OpenAPI 3.0 subset — the Phase-1 validator already
//! rejects keywords outside that subset (`$ref`, `oneOf`, etc.), so the
//! schema passed through here is already compatible by construction.
