mimo tts: empty audio data in response

Error message

mimo tts: empty audio data in response

What it means

MiMo TTS returned a 200 with parseable JSON but no audio: the choices array is empty or choices[0].message.audio.data is an empty string. Guard against synthesizing an empty/invalid voice message downstream.
