/**
 * Cloud STT engine.
 *
 * Records microphone audio to a WAV via `MicRecording`, then transcribes it
 * through a cloud provider (`transcribe.ts`, provider-agnostic). While
 * recording, it periodically re-transcribes the audio-so-far and emits that as
 * a partial, which keeps the live text stable and self-correcting (the provider
 * re-derives the whole utterance each tick). On stop it emits the final, most
 * accurate transcript.
 *
 * This preserves the original chunked-live behavior for non-macOS / cloud users
 * while keeping the controller engine-agnostic.
