   * We need Vitest to load the ESM build here in order to
   * use "vi.mock()" to mock the "node:events" imports to throw.
   * Vitest doesn't support module mocking in CommonJS.
   *
   * But aliasing the build isn't enough for it to function.
   * The root-level package.json is still CJS, which, I suspects,
   * resolves any subsequent in-build imports to their CJS counterparts.
