/**
 * Description:
 *   This script verifies the existence and content of build artifacts based on the
 *   provided CLI flags. It exists with exit code `0` if all verifications pass, otherwise
 *   with exit code `1`.
 *
 * Usage:
 *   node scripts/verify-build-artifacts.js [options]
 *
 * Options:
 *   --electron-unbundled    Verify artifacts for the unbundled Electron application.
 *   --electron-bundled      Verify artifacts for the bundled Electron application.
 *   --web                   Verify artifacts for the web application.
