Sunsetting Nuxt 3 support in the Frontic Nuxt Module

The module now requires Nuxt 4 and will no longer work with Nuxt 3 projects. Nuxt 3 users should stay on v0.6.x. If you're upgrading to Nuxt 4, update the module and review the changes below — some project structure adjustments are needed.

• Nuxt 4 required — Nuxt 3 support ends at v0.6.2. Install nuxt@4 before updating this module.
• Move your UI components — Under Nuxt 4, the default componentDir resolves to app/components/ui/ instead of components/ui/. Move your components into app/components/ui/, or set componentDir explicitly in your nuxt.config.ts to keep the old path.
• useAsyncData deduplication behaviour changed — Nuxt 4 now defers duplicate requests by default instead of cancelling them. Existing usages of useFronticPage, useFronticSearch, useFronticListing, and related composables may behave slightly differently when the same query runs concurrently.
