fix(release): build on macos-latest and read the model manifest on Windows

- GitHub no longer offers the macos-14 runner image: build the macOS
  installer on macos-latest (Apple Silicon), as Parler does.
- fetch-models imported models/manifest.json from its absolute path, which
  Node refuses on Windows (D:\…). Read and parse the file instead.
