trading_cycle()의 market_data에 보유 포지션 정보가 없어
Condition requires 'unrealized_pnl_pct' but key missing from market_data 경고 발생.
보유 종목(NVDA 등)의 take-profit/stop-loss 시나리오가 평가 불가하여 HOLD(confidence=0) 고착.

- get_open_position()에 timestamp 컬럼 추가
- market_data 구성 시 open_position 조회 후 아래 키 추가:
  - unrealized_pnl_pct: (current_price - entry_price) / entry_price * 100
  - holding_days: 매수일로부터 경과 일수
