What steps will reproduce the bug?
import { Socket } from 'node:net';
const socket = new Socket();
socket.on('error', (err) => {
console.log(err);
});
socket.on('connect', () => {
console.log('connected');
});
socket.connect({ host: 'google.com', port: 80 });
socket.once('close', () => {
console.log('closed');
socket.connect({ host: 'google.com', port: 80 });
});
socket.destroy();
How often does it reproduce? Is there a required condition?
Always

Additional information
Calling socket.destroySoon(); or socket.end(); does work as intended, but IMO socket.destroy(); should also allow a reconnect immediately afterwards. Note that calling socket.destroy(); on a socket that has been connected does allow for immediate reconnect afterwards as expected.

- 提交 Pull Request,并在描述里引用这个 Issue 编号。
调研方向
首先在报告的平台上复现提供的 node:net Socket 示例,然后跟踪 Socket 的 connect/destroy 生命周期以及堆栈跟踪中指定的 internalConnect 路径。当 destroy() 后立即重新连接能够在不出现 EALREADY 的情况下达到 connected,同时已连接时的 destroy-and-reconnect 行为保持不变,即表示完成。
