关闭文件描述符。除了可能的异常外，完成回调不会提供其他参数。

🌐 Closes the file descriptor. No arguments other than a possible exception are given to the completion callback.

对任何当前正在通过其他 fs 操作使用的文件描述符 (fd) 调用 fs.close() 可能导致未定义的行为。

🌐 Calling fs.close() on any file descriptor (fd) that is currently in use through any other fs operation may lead to undefined behavior.
