M7: 보석 상인 규칙·화면·테스트

- 규칙 모듈 packages/games/src/splendor: 카드 90장·귀족 10장 데이터 파일 분리(cards.ts),
  보석 가져오기(3색/같은 색 2개, allowFewerTokens), 예약(공개/더미, 황금), 구매(자동·수동 지불),
  10개 한도 반납, 귀족 방문·선택, 라운드 끝까지 진행 후 종료, 동점은 카드 적은 쪽,
  넘기기와 모두 넘기면 종료, 기권, 시간 초과 자동 행동(3번 연속이면 자리 비움),
  view는 더미·블라인드 예약·제외 귀족을 숨기고 살 수 있는 카드·지불 미리보기를 계산
- 테스트: 문서 10절 시나리오 42개 + 무작위 대국 1,000판(보존·정보 유출·onTimeout 합법·결정성)
  + 엔진 randomPlayout
- 화면 apps/web/src/games/splendor: 자체 카드·귀족·보석 그림(색+모양+글자), 3단계 시장과 더미,
  보석 은행, 내 보너스·보석·예약, 상대 요약, 살 수 있는 카드 강조, 반납·귀족 선택, PC/휴대폰·다크 모드
- 등록: GAMES, 카탈로그, 화면 레지스트리, 아이콘
- E2E: PC 방장 + 휴대폰 친구가 10점 판을 결과까지 진행
