Builds and packs the publishable packages, then installs the tarballs into
isolated directories outside the repository for local release testing.

Options:
  --out <dir>          Output directory. Defaults to a new directory under ${tmpdir()}
  --force              Remove --out first if it already exists
  --skip-check         Do not run npm run check before building
  --skip-test          Do not run ./test.sh after building
  --skip-install       Only create the artifact set; do not create isolated installs
  --skip-bun-install   Do not create the isolated Bun install
  --help               Show this help
