fix(#115): Implement proper cache invalidation strategy

[Killerjunior]

Closes #115

Summary

This PR addresses the critical issue where the application was implementing aggressive console overriding and error suppression mechanisms that masked critical runtime errors and compromised production debugging capabilities.

Problem Statement

The previous implementation was:

• Suppressing critical runtime errors
• Making production debugging impossible
• Increasing mean time to resolution (MTTR) for incidents
• Creating potential security vulnerabilities from suppressed error information
• Providing poor developer experience and onboarding challenges

Solution Implemented

🗑️ Removed Problematic Files

• Deleted src/utils/consoleOverride.ts
• Deleted src/utils/manualErrorSuppressor.ts

🧪 Testing

• Created comprehensive test suite (src/utils/errorHandlingTest.ts)
• Verified console override removal
• Tested structured logging functionality
• Validated error monitoring capabilities
• Confirmed performance monitoring works

📝 Migration Guide

For Existing Code

1. Replace console.log() → structuredLogger.info()
2. Replace console.error() → structuredLogger.error()
3. Add error boundaries around critical components
4. Implement proper error categorization

For New Development

1. Use structured logging from the start
2. Implement error boundaries for major features
3. Add performance monitoring for critical operations
4. Configure appropriate log levels per environment

🔮 Future Enhancements

• Integration with external services (Sentry, LogRocket)
• Advanced error analytics and trend analysis
• Automated alerting (Slack/Email notifications)
• Real-time error monitoring dashboard
