🎯 Enhance GAIA Agent for 70%+ accuracy with advanced optimization

- Add multi-attempt strategy with retry logic for higher accuracy
- Implement intelligent answer validation based on question types
- Optimize model selection prioritizing high-performance providers
- Enhanced validation for counting, date, and name-based questions
- Update performance expectations from 40% to 70%+ accuracy target
- Apply optimizations to both root and deployment app versions
