PHP 8.2+ deprecation: Creation of dynamic property is deprecatedhttps://www.drupal.org/docs/develop/issues

Problem/Motivation

PHP 8.2 deprecated dynamic properties (creating class properties on-the-fly without declaring them). The Drupal\entity_sync\DelayedExecutor\Executor class assigns $this->exportManager and $this->queueManager in the constructor without declaring these properties, causing deprecation warnings:

Deprecated function: Creation of dynamic property Drupal\entity_sync\DelayedExecutor\Executor::$queueManager is deprecated

Steps to reproduce

1. Run PHP 8.2 or higher
2. Enable entity_sync module
3. Trigger any action that instantiates the DelayedExecutor\Executor service
4. Observe deprecation warning in logs

Proposed resolution

Add explicit property declarations to the Executor class:

/**
 * The Entity Synchronization entity export manager.
 *
 * @var \Drupal\entity_sync\Export\EntityManagerInterface
 */
protected $exportManager;

/**
 * The Entity Synchronization queue manager.
 *
 * @var \Drupal\entity_sync\Queue\ManagerInterface
 */
protected $queueManager;
