openai.internal._chat_audio_format
(internal) `input_audio.format` is the mime subtype, with the one alias the API needs. Unknown subtypes are forwarded rather than rejected: OpenAI documents wav/mp3 but transcodes others, and a compatible server may accept more (this is the engine's behaviour; sys_llm hard-errored on anything but wav/mp3).
