Environment

h3 2.0.1-rc.22
node v24.15.0

Reproduction

// server.mjs
import { H3, serve, writeEarlyHints } from "h3/node";

const app = new H3().get("/", async event => {
	await writeEarlyHints(event, {});
	return "⚡️ Tadaa!";
});

serve(app, { port: 3000 });

Or clone repo from here https://github.com/pajecawav/h3-early-hints-bug and run pnpm install && node server.mjs

Describe the bug

When using writeEarlyHints with Node runtime promise never resolves so the request handler hangs indefinitely
