tanstack-vue-table-migrate-v8-to-v9

Use this as the complete breaking-change checklist. V9 is the current API; do not stop after renaming the Vue composable.

Framework prerequisite: Vue 3.2 or newer (vue >=3.2).

Recommended Migration Order

1. Replace useVueTable with useTable while preserving reactive inputs.
2. Define explicit features, then move row models and registries into tableFeatures.
3. Update state reads, controlled ownership, and rendering.
4. Apply every shared API and type rename below.
5. Use stockFeatures only as a temporary audit bridge; explicit features are the production target.
