The openai provider implements transcribeAudio via
transcribeOpenAiCompatibleAudio (Whisper API), but its capabilities
array only declared ["image"]. This caused the media-understanding
runner to skip the openai provider when processing inbound audio
messages, resulting in raw audio files being passed to agents
instead of transcribed text.
Fix: Add "audio" to the capabilities array so the runner correctly
selects the openai provider for audio transcription.
