위협 가이드 제거: 오목 위험 자리, 체스·장기 위험 기물 경고, 바둑 단수 경고

- 오목: 상대 3·4를 막으라는 빨간 동그라미·노란 점선(hints 옵션, view.hints, threatHints) 삭제
- 체스·장기: hints 'movesAndThreats'(주황 점선 위험 기물) 삭제 → 'off' / 'moves'만 남김
- 바둑: atariWarning 옵션과 atariWarnings(깜빡이는 단수 돌) 삭제
- 도움말 문구·설정 화면·docs 정리, 테스트는 "어떤 view에도 위협 표시 없음"으로 바꿈
- 갈 수 있는 칸 점, 금수 ×, 둘 수 없는 점 같은 규칙 표시는 그대로
