v1.9.0 — Voice console (opt-in)
Adds the voice-driven compliance console at python -m shasta.voice.
Browser-direct WebRTC to OpenAI Realtime API; FastAPI backend mints
ephemeral tokens and serves 14 tool endpoints over real ShastaDB data.
Voice handles read-side queries plus light writes to the risk register;
heavy operations remain in Claude Code skills.
Install: pip install shasta[voice]
