/v1/audio/speaker-embeddings gains window (seconds) + step (default = window):
returns one embedding per sliding window, each tagged start/end, instead of a
single whole-file embedding. Implemented in the pyannote worker's /embed via
_crop_wav over the cached embedder; client + endpoint pass the params through;
whole-file mode and enroll/identify/verify are unchanged.
