Adds the studio-server side of the voiceover spectral-carve pipeline: - vstSidecar.ts spawns and supervises the hyperframes-vst host process, resolving it from the published PyPI package (uvx, or an explicit HYPERFRAMES_VST_HOST override), and requires a shared-secret token on the WebSocket so a local port can't be driven by another process on the box. - vstCarve.ts + POST /vst/carve run voiceover analysis and return carve bands. - The CLI re-exports the sidecar through @hyperframes/studio-server/vst-sidecar so preview can stop the process on shutdown, and the Vite dev adapter threads the auth token through to the browser. The host itself is not vendored: it is an external Python package with its own release cadence, so depending on the published build keeps plugin-host upgrades out of this repo's release train.
