fix: Cannot start nuxt: Failed to get devtools context

🐛 The bug

When using (the latest version of) Nuxt Devtools and Nuxt Seo, Nuxt won't start in dev mode. See also https://github.com/harlan-zw/nuxt-seo/issues/242

// package.json
{
  "name": "nuxt-app",
  "private": true,
  "type": "module",
  "scripts": {
    "build": "nuxt build",
    "dev": "nuxt dev",
    "generate": "nuxt generate",
    "preview": "nuxt preview",
    "postinstall": "nuxt prepare"
  },
  "dependencies": {
    "@nuxtjs/seo": "^2.0.0-rc.16",
    "nuxt": "^3.12.4",
    "vue": "latest"
  }
}

// nuxt.config.ts
export default defineNuxtConfig({
  compatibilityDate: '2024-04-03',
  devtools: { enabled: true },
  modules: ["@nuxtjs/seo"]
})

Gives error

 ERROR  Cannot start nuxt:  Failed to get devtools context.                                                                                                                                                                                                                                                                               12:05:49 PM

The stackblitz reproduction is giving a different error though (it wont start either)

🛠️ To reproduce

https://stackblitz.com/edit/nuxt-starter-rbifnw?file=nuxt.config.ts

🌈 Expected behavior

I excepted the dev server to start with devtools enabled :)

ℹ️ Additional context

I first reported this bug in the nuxt seo repo, but according to @harlan-zw it's an upstream issue...

Reproduce the failure using package.json and nuxt.config.ts with Nuxt Devtools and @nuxtjs/seo enabled. Start with the extendServerRpc stack entry in @nuxt/devtools-kit and the @nuxtjs/robots call site, then compare the local and StackBlitz errors. Done means the Nuxt development server starts with devtools enabled.
