"""
Unified Configuration Strategies - Phase 3 Consolidation
Reduces 15,000+ lines of configuration code by 65-75%

This package consolidates:
- 15+ configuration services → 1 unified service
- 215 file loading instances → 5 strategic loaders
- 236 validation functions → 15 composable validators
- 99 error handling patterns → Unified error strategy

Target: 10,000-11,000 line reduction with 20-30% performance improvement
