Describe the bug

If using the render:response and afterResponse hooks in the server plugin, the statusCode doesn't match the one actually sent.

// File: server/plugins/OnResponsePlugin.ts

export default defineNitroPlugin((nitroApp) => {
  nitroApp.hooks.hook('render:response', (response) => {
    console.log('[render:response] statusCode:', response.statusCode); // always 200
  });

  nitroApp.hooks.hook('afterResponse', (event) => {
    console.log('[afterResponse] statusCode: ' + event.node.res.statusCode); // always 200
  });
});

Would you see if you can reproduce this in pure Nitro (reproduction sandbox), and if so, raise there? 🙏

Hmm... Nitro doesn't hook the render:response (which is okay) and afterResponse, but in the beforeResponse hook this bug repeats, also returning a status code of 200. See Nitro's reproduction.

UPD: It looks like a bug in unjs/h3. I have created an issue for this.
