// check-i18n.cjs 的门禁自测:用 node 内置测试跑,不引第三方依赖。
//   node --test scripts/check-i18n.test.cjs
//
// 覆盖(对应 2026-10-10 对抗审查发现的假阴性 + 常规门禁行为):
//   ① 单引号值含裸 @ → 报错
//   ② 双引号值含裸 @ → 报错
//   ③ 反引号模板字面量含裸 @ → 报错(原实现只匹配引号,漏报)
//   ④ 含 ${} 插值不误报(模板字面量里的插值需先占位再编译)
//   ⑤ 转义写法 {'@'} → 通过
//   ⑥ 含 | 与裸 {} 的用例
// 另附 scanDirectory 对临时目录样本的端到端断言。
