 * WeldLog Save Trigger - Refactored Version
 * 
 * This file is the entry point for all weld log save triggers.
 * All trigger logic has been extracted to separate classes in:
 * app/Services/WeldLogTriggers/Triggers/
 * 
 * The trigger system uses:
 * - WeldLogTriggerInterface: Contract for all triggers
 * - BaseTrigger: Base class with common functionality
 * - WeldLogTriggerRegistry: Central registry for all triggers
 * - WeldLogTriggerManager: Orchestrates trigger execution
 * 
 * @see app/Services/WeldLogTriggers/
