The Schema\Blueprint class currently exposes searchIndex() / dropSearchIndex() for Atlas Search and vectorSearchIndex() for Atlas Vector Search. Adding shorter aliases improves developer experience and API consistency, while deprecating the verbose vectorSearchIndex() method.

Changes:
* Add vectorIndex(array $definition, string $name = 'default') as an alias for vectorSearchIndex(), which will be deprecated
* Add dropVectorIndex(string $name) as an alias for dropSearchIndex() scoped to vector indexes
* Deprecate vectorSearchIndex() in favor of vectorIndex()

Proposed API:

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

Schema::table\('collection', function \(Blueprint $collection\) {
    $collection\->dropVectorIndex\('my\_vector\_index'\);
}\);
