Enhance CDN File Error Handling and Logging Infrastructure

Description

Summary of Work

This pull request introduces a robust error management system for our CDN file retrieval service, focusing on improved reliability, traceability, and developer experience.

Project Evolution:
Our CDN file service now features a comprehensive error handling framework that provides:

• Standardized error response mechanisms
• Detailed error logging and tracking
• Type-safe file access error management
• Enhanced system resilience and observability

Key Architectural Improvements:

• Centralized error response utility
• Custom error classes for specific scenarios
• Flexible logging mechanism with contextual information
• Improved error propagation and handling strategies

Business and Technical Benefits:

• Reduced system downtime through precise error identification
• Simplified debugging and monitoring processes
• Enhanced security through granular file access controls
• Improved developer experience with consistent error handling

Future Roadmap:

• Integrate with advanced monitoring systems
• Expand error type coverage
• Implement more granular access control mechanisms
