/**
 * STT orchestrator — `transcribe()` is the single entry point used by channel
 * adapters (telegram, webchat) and the preflight router.
 *
 * Internally delegates to `runAudioTranscription` from the media-understanding
 * runner. The runner returns a `MediaUnderstandingDecision`; we translate each
 * `decision.attachments[0].attempts[]` entry into the `STTProviderAttempt`
 * shape consumed by downstream telemetry.
 *
 * One-attachment fast path: `transcribe()` is 1-buffer-in / 1-text-out, so we
 * wrap the input as a single CapabilityAttachmentInput and unpack the first
 * output. Multi-attachment cases go through `runAudioTranscription` directly.
