- 包声明 type:module 时 .js 产物被 Node 按 ESM 解析：Node 16/18 下 require 报 ERR_REQUIRE_ESM，Node 20+ 拿到 namespace 对象（success/version 等属性 undefined） - dist/metona-toast.cjs.js → .cjs，dist/react.cjs.js → .cjs - 主包 CJS footer 将 default 提升为 module.exports：require() 直接返回 MeToast（兼容 .default / .MeToast / .Met / .Toast / .VERSION 所有用法） - 版本 0.5.1（0.5.0 已发布带问题产物） - 真实消费者验证：CJS/ESM/React 子包四路加载全部正常

* 环境隔离测试 — 需要切换 document/window/localStorage 环境并调用 jest.resetModules()。
|

* 独立成文件：resetModules 会清空模块缓存，若与其他测试同文件会导致
|
||
* 后续 require 拿到新模块实例、与 import 时绑定的实例状态分裂。
|
||
* 注：jsdom 以 getter 暴露 document/window，普通赋值无效，须用 defineProperty 覆盖。
