// Shared helper for spawning npm from the repo's tools/ scripts.
//
// On Windows `npm` resolves to the `npm.cmd` batch shim, which Node refuses
// to spawn without a shell (`spawn EINVAL`). Node also warns when args are
// passed alongside `shell: true` (DEP0190), so the command line is joined
// here; args must be plain words that need no quoting.
