@hono/node-server has Denial of Service risk when receiving Host header that cannot be parsed

Impact

The application hangs when receiving a Host header with a value that @hono/node-server can't handle well. Invalid values are those that cannot be parsed by the URL as a hostname such as an empty string, slashes /, and other strings.

For example, if you have a simple application:

import { serve } from '@hono/node-server'
import { Hono } from 'hono'

const app = new Hono()

app.get('/', (c) => c.text('Hello'))

serve(app)

Sending a request with a Host header with an empty value to it:

curl localhost:3000/ -H "Host: "

The results:

node:internal/url:775
    this.#updateContext(bindingUrl.parse(input, base));
                                   ^

TypeError: Invalid URL

}
