[dev] Unhandled 404 error on `/_nuxt/` request in NuxtDevServer.toNodeHandle

[mrnasil]

Environment

 - Operating System: Windows 11
 - Node Version: v25.1.0
 - Nuxt Version: 4.3.0
 - @nuxt/cli Version: 3.32.0
 - Package Manager: pnpm

 ### Reproduction
 During development, occasionally get this error in console:

ERROR [request error] [unhandled] [GET] http://localhost:3000/_nuxt/

⁃ at createError (node_modules/@nuxt/cli/dist/dev-KB30iboK.mjs:54:14)
⁃ at NuxtDevServer.toNodeHandle (node_modules/@nuxt/cli/dist/dev-KB30iboK.mjs:264:18)

[CAUSE]
{
status: 404,
}

 ### Describe the bug
 Random 404 errors appear in the dev server console when accessing `/_nuxt/` path. This seems to happen during hot reload or page
  navigation. The application continues to work but the error is logged.

 ### Expected behavior
 No 404 errors should be thrown for internal Nuxt dev server paths.
