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'\);
}\);
