Key fixes:
- ExchangeInterface: Remove stale entries before creating new exchange connections
- LiveBroker: Optimize get_total_equity() to price only top 10 assets (was hanging on 462 testnet assets)
- LiveBroker: Add fiat currency skip list to avoid failed price lookups
- PythonGenerator: Fix market symbol regex to handle 2-5 char symbols (BTC/USDT)
New features:
- LiveStrategyInstance: Full live trading strategy execution
- Circuit breaker and position limits for live trading safety
- Restart-safe order reconciliation via client order IDs
Verified working:
- Live strategy starts on Binance testnet
- Orders placed and filled successfully
- Execution loop runs with active strategies

Phase 5 - Live Trading (stub implementation):
- Create LiveBroker stub with NotImplementedError for all methods
- Document required exchange API integration points
- Add testnet flag for safety
Phase 6 - Observability:
- Add structured logging with StructuredFormatter and ColoredFormatter
- Create TradingLogger for trading-specific log entries
- Implement health check system with HealthCheck class
- Add default health checks for database, exchange, memory
- Create health_endpoint() for monitoring integration
The LiveBroker is a stub that needs exchange API integration
for production use. All other trading modes (backtest, paper)
are fully functional.
