pacnpal a4ca6e8ea6 Core Systems:
Component-based architecture with lifecycle management
Enhanced error handling and recovery mechanisms
Comprehensive state management and tracking
Event-driven architecture with monitoring
Queue Management:

Multiple processing strategies for different scenarios
Advanced state management with recovery
Comprehensive metrics and health monitoring
Sophisticated cleanup system with multiple strategies
Processing Pipeline:

Enhanced message handling with validation
Improved URL extraction and processing
Better queue management and monitoring
Advanced cleanup mechanisms
Overall Benefits:

Better code organization and maintainability
