## ✨ Added

### LLM-Powered Strategy Generation
- **StrategyOrchestrator**: Generate trading strategies by combining factors with LLM
- **Local llama.cpp Support**: Run strategy generation locally (Qwen3.5-35B)
- **OpenRouter Support**: Optional cloud model fallback
- **Improved Prompts (v3)**: IC-sign-aware factor combination instructions
- **Diverse Factor Selection**: Automatic selection by type (momentum, divergence, volatility, session)

### Realistic Backtesting
- **OHLCV-Based Returns**: Real price returns instead of factor proxies
- **Spread Costs**: 1.5 bps per trade deducted from returns
- **Forward-Fill Support**: Daily factors → 1-min frequency
