Dependency conflict with firebase-functions@7.x when installing nuxt-vuefire

[Tkkg1994]

Reproduction

Steps to reproduce the bug

1. Create a new Nuxt project (or use an existing one).

2. Install Firebase Functions v7:

   npm install firebase-functions@^7.0.0

3. Install VueFire for Nuxt:

   npm install nuxt-vuefire@^1.1.0

4. Observe the dependency resolution error.

Expected behavior

nuxt-vuefire should install successfully and support the latest
Firebase Functions release (firebase-functions@7.x) without requiring
--force or --legacy-peer-deps.

Actual behavior

Installation fails due to a peer dependency conflict:

npm ERR! ERESOLVE could not resolve
