Kotlin Multiplatform 네이티브 앱으로 전환 (Android + iOS 공용 코드)

TWA 래퍼를 걷어내고 Compose Multiplatform 으로 다시 만들었다. 엔진·UI·모드
전부 commonMain 한 벌이라 Android 와 iOS 가 같은 코드를 쓴다.

- engine/: 웹 JS 엔진을 Kotlin 으로 이식 (SRS+180 킥, 7-bag, T-spin, B2B,
  콤보, All Clear, 점수·레벨). commonTest 28개 통과
- game/: 모드 규칙 + 중력/락딜레이/DAS/ARR 타이밍
- ui/: 네오브루탈 컴포넌트, 메인/솔로시트/인게임/결과/설정
- ui/Responsive.kt: 고정 해상도를 버리고 가용 크기에서 셀 크기·배율 계산.
  폰 세로, 플립 초세로, 플립 커버(소형), 폴드 펼침, 태블릿/아이패드 가로 대응
- androidMain: resizeableActivity + configChanges 로 접기/펴기·회전 시 재시작 없음
- iosMain + iosApp/: MainViewController + SwiftUI 껍데기 + XcodeGen 설정
  (실제 iOS 빌드는 macOS + Xcode 필요)
- scripts/release.sh: 버전 상승 → 테스트 → 서명 빌드 → 태그 → Gitea 릴리스 자동화
