adk-model 0.8.4

//! OpenAI schema adapters for function-calling APIs.
//!
//! Provides two adapters:
//!
//! - [`OpenAiStrictSchemaAdapter`]: For OpenAI strict mode — preserves `$ref`/`$defs`,
//!   `anyOf`/`oneOf`, and type arrays while recursively injecting
//!   `additionalProperties: false` on all object schemas.
//!
//! - [`OpenAiSchemaAdapter`]: For OpenAI non-strict mode — applies minimal safe fixes
//!   without destroying schema semantics. Does NOT remove `$ref`, `$defs`, `anyOf`,
//!   `oneOf`, `additionalProperties`, or collapse type arrays.
//!
//! Both adapters share the same allowed format list as Gemini:
//! `date-time`, `date`, `time`, `email`, `uri`, `uuid`, `int32`, `int64`, `float`, `double`.
