- executeCloseLong/CloseShort: cancel stop-loss and take-profit orders BEFORE closing
position to prevent orphaned orders from triggering and creating unintended positions
- emergencyClosePosition: same fix for drawdown monitor's emergency close path
- Skip SetStopLoss/SetTakeProfit when AI returns price=0 (prevents exchange API errors)
Also includes:
- Add agent.Stop() to graceful shutdown sequence in main.go
