## Issue #9: Implement Error Handling and Logging

### Description

Implement comprehensive error handling and logging mechanisms to improve application stability and debugging capabilities.

### Acceptance Criteria

- [ ] Create centralized error handling middleware
- [ ] Implement structured logging
- [ ] Add error reporting to monitoring system
- [ ] Ensure all API endpoints handle errors gracefully
- [ ] Log important application events

### Tasks

- [ ] Create `src/middleware/error-handler.js`
- [ ] Implement Winston or Bunyan logging
- [ ] Add error response format
- [ ] Integrate logging with API endpoints
- [ ] Set up log aggregation and monitoring

### Notes

This issue addresses the need for robust error handling and logging to improve application stability. The implementation will include centralized error handling middleware, structured logging, and integration with monitoring systems to track application health and debug issues effectively.
