Summary

Adds upstream_driver option for CLIENT SETINFO LIB-NAME to allow upstream libraries to identify themselves, per Redis client guidelines.

Usage

// String
$client = new Client($params, [
    'upstream_driver' => 'laravel_v11.0.0',
]);
// → CLIENT SETINFO LIB-NAME predis(laravel_v11.0.0)

// Array (for multiple upstream drivers)
$client = new Client($params, [
    'upstream_driver' => ['laravel_v11.0.0', 'my-app_v1.0.0'],
]);
// → CLIENT SETINFO LIB-NAME predis(laravel_v11.0.0;my-app_v1.0.0)

When not specified, sends predis (current behavior unchanged).
