在 Node.js 环境退出时完成

¥Finalization on the exit of the Node.js environment

Node.js 环境可能会在任意时间尽快拆除，不允许 JavaScript 执行，就像 worker.terminate() 的请求一样。当环境被拆除时，JavaScript 对象、线程安全函数和环境实例数据的已注册 napi_finalize 回调将立即独立调用。

¥The Node.js environment may be torn down at an arbitrary time as soon as possible with JavaScript execution disallowed, like on the request of worker.terminate(). When the environment is being torn down, the registered napi_finalize callbacks of JavaScript objects, thread-safe functions and environment instance data are invoked immediately and independently.

napi_finalize 回调的调用安排在手动注册的清理钩子之后。为了确保在环境关闭期间插件完成的正确顺序以避免 napi_finalize 回调中的释放后使用，插件应该向 napi_add_env_cleanup_hook 和 napi_add_async_cleanup_hook 注册一个清理钩子，以便以正确的顺序手动释放分配的资源。

¥The invocation of napi_finalize callbacks is scheduled after the manually registered cleanup hooks. In order to ensure a proper order of addon finalization during environment shutdown to avoid use-after-free in the napi_finalize callback, addons should register a cleanup hook with napi_add_env_cleanup_hook and napi_add_async_cleanup_hook to manually release the allocated resource in a proper order.
