patch

Convert audio file parts in prompts into OpenRouter input_audio content blocks.

Previously, every non-image file part was converted into a generic file content block. OpenRouter only accepts audio as base64-encoded input_audio content parts, so audio attachments were rejected or mishandled by the upstream provider.

Audio file parts with a recognized mediaType (aac, aiff, flac, m4a, mp3, ogg, pcm16, pcm24, and wav) are now converted into input_audio blocks. Unsupported audio media types and URL audio data fail with an AiError since OpenRouter requires base64-encoded audio data and does not fetch audio URLs.
