Task: Implement Comprehensive Error Handling System

Description

Design and implement a robust error handling system for the orchestrator that provides clear, actionable error messages and proper error propagation throughout the application layers.

Objectives

• Create a centralized error module in src/error/
• Implement custom error types for different components (resource, client, service, controller)
• Ensure proper error propagation between layers
• Add context to errors for better debugging
• Implement error logging with appropriate severity levels
• Add error recovery mechanisms where applicable

Implementation Details

• Define a base OrchestratorError enum that can wrap errors from different components
• Implement From traits for common error types
• Add context information to errors (file, line, operation description)
• Ensure all public functions return Result<T, OrchestratorError>
• Add helper macros for error creation and propagation

Acceptance Criteria

• All errors are properly typed and provide meaningful messages
• Errors include context about where they occurred
• Error handling doesn't significantly impact performance
• Errors are properly logged with appropriate severity
• Critical errors trigger appropriate recovery mechanisms

Dependencies

• None (this should be implemented first)
