Laravel 13.x introduces Schema::ensureVectorExtensionExists() to verify that the vector extension is available before creating vector columns/indexes (PostgreSQL: checks pgvector). For MongoDB, the equivalent is to check that Atlas Search is available on the current connection.

Proposed implementation:

The method should attempt a lightweight Atlas Search operation (e.g. listSearchIndexes) and throw a descriptive exception if Atlas Search is not supported, reusing the existing Builder::isAtlasSearchNotSupportedException() logic.

// Throws if Atlas Search is not available (not an Atlas cluster)
Schema::ensureVectorExtensionExists();

Schema::create('collection', function \(Blueprint $collection\) {
    $collection->vectorIndex([...], 'my_vector_index');
});
