/**
 * AudioDiarization — speaker diarization via the server's
 * /v1/audio/diarizations route.
 *
 * The browser SDK is server-route-only; there is no local C-ABI native
 * execution. This facade POSTs PCM-f32 audio bytes (as base64) to the
 * hosted native backend (pyannote pipeline) and returns typed speaker
 * segments.
 *
 * Python reference: octomil-python/octomil/audio/diarization.py
 * Route: POST /v1/audio/diarizations (octomil-python/octomil/serve/app.py:1488)
 *
 * Request body:
 *   { audio_pcm_f32_base64: string, sample_rate_hz: number, deadline_ms?: number }
 *
 * Response body:
 *   { object: "audio.diarization", sample_rate_hz: number,
 *     segments: DiarizationSegment[] }
