Subject: [PATCH] Handle tie games in KBO schedule parsing and result
 processing.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- KBO 경기 결과 파싱 시 무승부(`draw`) 상황의 점수도 추출할 수 있도록 정규표현식을 개선하여 경기 상태가 'scheduled'로 오분류되는 문제를 해결했습니다.
- 승리 팀 코드(`winningTeamCode`)가 없는 무승부 경기에서도 결과 처리가 정상적으로 수행되도록 서비스 레이어의 예외 처리를 수정했습니다.
- 무승부 시 어느 팀에 투표했더라도 모두 정답(`result: true`)으로 처리되도록 투표 결과 정산 및 자가 치유(reconcile) 로직을 업데이트했습니다.
