Trading Orchestrator - Main Decision Making Module

This is the core orchestrator that:
1. Coordinates CNN and RL modules via model registry
2. Combines their outputs with confidence weighting
3. Makes final trading decisions (BUY/SELL/HOLD)
4. Manages the learning loop between components
5. Ensures memory efficiency (8GB constraint)
