VoiceVerify used a fixed distance of 0.5 when the request had none. Read
voice_verify_threshold, a distance in (0, 2), from the model options and
keep 0.5 as the default. The real-library spec now cuts clips from a
two-voice recording and checks the bundle embedding size, the encoder
identity, determinism and the same-voice versus different-voice distance.

Bind parakeet_capi_speaker_embed_pcm and parakeet_capi_free_floats with a
Dlsym probe and implement VoiceEmbed on the speaker context, so a model
with a speaker_model or a bundle speaker_component can serve the
realtime voice_recognition stage and /v1/voice/*. The response carries
the sha256 identity of the encoder weights.
VoiceVerify embeds both clips and compares them by cosine distance. It
refuses anti_spoofing because there is no such head.
A libparakeet.so without the symbols answers Unimplemented, and a model
without a speaker encoder answers FailedPrecondition.
