/**
 * Links the local npm-packages/meteor-rspack into a Meteor app so it runs
 * against the latest dev version.
 *
 * Steps:
 *   1. Run `meteor update --npm` in the app
 *   2. Install the matching @rspack/core and @rspack/cli versions into the
 *      local meteor-rspack package (read from packages/rspack/lib/constants.js)
 *   3. Install `ignore-loader` in the app
 *   4. `npm link` the local meteor-rspack into the app
