## Description
Enforce opting in to Vue Vapor mode in `<script setup>` blocks.

Vue 3.6 introduces an opt-in “Vapor mode” for SFC `<script setup>` blocks:
`<script setup vapor>`.

Vapor mode only works for Vue Single File Components (SFCs) using `<script setup>`.

This rule reports `<script setup>` opening tags that are missing the `vapor` attribute.

## Examples

### Invalid

```vue
<script setup>
</script>
<pre class="language-text"><code class="language-text"></code></pre>

Valid

vue
<script setup vapor>
</script>
  • noVueOptionsApi: Disallows the Options API format, which is incompatible with Vapor Mode
