POST /v1/voices registers a voice from a WAV extracted server side
through qt_extract_voice_ref or from pre extracted .spk and .rvq
latents taken verbatim, DELETE drops it and GET lists it alongside the
model speakers. A registered voice wins over a speaker of the same
name and injects the reference latents into qt_tts_params, ref_text
present selects ICL clone mode. The registry lives in process RAM
under the synthesis mutex, so registration and lookups never race a
running synthesis. The audio and rvq readers gain buffer variants
factored from the file paths. The README and the architecture
document catch up on the streaming decode, the hidden bridge, and the
server endpoints.
