https://{host}/feed/{feedId} 앱 링크를 수신해 피드 상세로 이동한다.
인증 게이트를 통과한 뒤 한 번만 소비하도록 pending 저장소를 둔다.

인증 게이트 판정에 `::class.qualifiedName`을 쓰지 않는다. route 문자열은
@Serializable이 컴파일 시점에 박은 원본 FQN인데 R8은 클래스를 난독화하므로
release에서 둘이 절대 같아지지 않는다. 게이트가 항상 열린 상태가 되어
스플래시 위에서 상세로 이동한 뒤 스플래시의 홈 이동이 그것을 덮어써
콜드 스타트 딥링크가 유실됐다. NavDestination.hasRoute로 교체한다.

같은 원인으로 release에서 깨지던 홈 BackHandler, 스플래시·로그인
전체화면 판정, TTFD의 스플래시 제외도 함께 고친다.

--- 리베이스 충돌 해결 (#149 병합 이후) ---

develop에 머지된 #149가 같은 자리에 푸시 라우팅용 싱글톤 스토어를 도입해,
같은 역할의 스토어가 둘이 되는 충돌이 났다. 하나로 합쳤다.

- 스토어를 core/common/deeplink로 통일한다. feature/auth의 스플래시가
  hasPending을 읽어야 해서 app 모듈에는 둘 수 없다.
- PendingFeedDeepLink(#146) + PendingPushNavigation(#149) → PendingNavigation.
  destination을 갖고 있어 앱 링크(항상 FEED_DETAIL)와 푸시(FEED_DETAIL·HOME·
  FEED_CREATE)를 함께 표현한다.
- PushDestination enum → NavigationDestination으로 옮긴다. 앱 링크도 쓰는
  개념이라 push에 매인 이름이 맞지 않는다. FCM screen 문자열 해석은 FCM
  관심사라 pushDestinationOf는 app/notification에 남긴다.
- handleFeedDeepLink(#146) + handlePushNavigation(#149) →
  handleNavigationIntent. Uri를 FCM extras보다 먼저 보는 #146의 순서를
  유지해 앱 링크 유입이 push_opened를 오염시키지 않는다.

빌드 검증: assembleDebug / assembleRelease / 단위 테스트 전부 통과.

앱 링크를 받는 쪽은 만들었지만 링크를 만들어 내보내는 경로가 없었다.
더보기 메뉴에 공유하기를 넣어 시스템 공유 시트로 링크를 내보낸다.

  소유자: 공유하기 · 삭제하기
  타인:   공유하기 · 신고하기 · 차단하기

- feedShareTextOf를 core/common/deeplink에 둔다. 링크를 만드는 규칙과 읽는
  규칙(feedIdFromAppLink)이 어긋나면 공유 링크가 홈으로 떨어지므로 한 파일
  옆에 두고, FEED_PATH_SEGMENT를 internal로 올려 같은 상수를 공유한다.
  왕복 테스트(만든 링크를 파서가 다시 읽는다)로 두 규칙을 묶어둔다.
- 제목을 URL 앞에 싣는다. OG 미리보기가 뜨지 않는 환경(문자·일부 앱)에서도
  무엇을 물어보는지 전달돼야 한다. 제목이 비었거나 공백뿐이면 URL만 보낸다 —
  따옴표만 남은 텍스트가 나가면 안 된다.
- 공유 실행은 BuyOrNotNavHost에서 한다. host가 app 모듈의 BuildConfig에만
  있고, onLinkClick·onImageClick이 이미 같은 층을 탄다.
- share_clicked(feed_id, is_owner)를 ViewModel에서 발행한다. 시스템 시트의
  선택 결과는 앱으로 돌아오지 않으므로 «공유 의도»까지만 측정한다 — 실제
  도달은 반대편 app_link_opened로 보고 두 이벤트를 이어 퍼널을 만든다.
- feature/notification에 core:analytics 의존성을 추가했다.

검증: 단위 테스트 7건(제목 유무·공백·왕복), assembleDebug/Release,
실기기에서 타인 피드 공유 → 시트에 «'제목' 살까 말까?\n{url}» 표시,
share_clicked 1회(is_owner=false). 나머지 조합은 수동 테스트로 확인.

서버 계약 확인 결과(BuyOrNot-BE):

- Feed.isGuestPost()는 user == null이고, FeedResponseV2.buildAuthorResponse가
  이 글의 작성자를 FeedAuthorResponse(0L, ...)로 내려준다.
- 차단은 POST /api/v1/users/blocks/{userId}로 실제 User를 대상으로 한다.
  userId=0으로는 성립하지 않으므로 항목을 누르면 실패할 수밖에 없다.
- 신고는 POST /api/v1/feeds/{feedId}/report로 피드를 대상으로 한다.
  비회원 글에도 유효해서 그대로 남긴다.

Author.isGuest를 도메인에 두어 판별 규칙(userId == 0)을 한 곳에서 정의하고,
FeedCard는 canBlock 플래그만 받는다. designsystem이 서버 계약을 알 필요가 없다.

로그인 화면의 «비회원으로 시작하기»와, 게스트에게만 보이던 홈 TopBar를 없앤다.

skipLogin()이 UserType.GUEST를 저장하고 홈으로 보내는 유일한 게스트 진입
경로였다. 이 버튼을 없애면 스플래시가 GUEST를 로그인 화면으로 보내므로
게스트는 홈에 도달할 수 없다 — 따라서 홈의 GuestTopBar 분기는 죽은 코드가
된다. 함께 걷어냈다.

- LoginScreen: 버튼 + onGuestStartClick 체인 제거
- LoginContract/ViewModel: LoginIntent.SkipLogin과 skipLogin() 제거
- HomeScreen: HomeTopBarSection의 userType 분기를 없애고 HomeTopBar만 남긴다.
  이제 죽은 onLoginClick 콜백 체인(HomeRoute → HomeScreen → content)과
  HomeNavigation·BuyOrNotNavHost의 배선도 제거
- designsystem: GuestTopBar 컴포넌트와 프리뷰 삭제, BuyOrNotErrorView의
  프리뷰 2곳은 HomeTopBar로 교체

UserType.GUEST 자체는 남겨둔다 — 게스트 투표 API(voteGuestFeed)와 탭 제한,
비회원 글 판별(Author.isGuest)에 계속 쓰인다.

검증: assembleDebug / assembleRelease / 단위 테스트 통과.

**1. NavigationDestination → EntryDestination**

#149(푸시 라우팅)와 합친 뒤 이 enum이 앱 링크와 푸시 양쪽에서 쓰이게 됐다.
PushDestination은 앱 링크 유입에 맞지 않았고, NavigationDestination은
androidx의 NavDestination과 한 파일에 공존해 혼동을 만들었다.

  BuyOrNotApp.kt
    import androidx.navigation.NavDestination.Companion.hasRoute
    import ...deeplink.NavigationDestination   ← 둘 중 어느 쪽인지 매번 확인해야 했다

«외부에서 앱에 진입할 때의 목적지»라는 실제 의미를 담고 androidx와 충돌하지
않는 이름으로 바꿨다. HOME(마케팅 푸시)처럼 딥링크가 아닌 값도 포괄한다.
FCM screen 문자열 해석은 푸시 관심사라 pushDestinationOf는 그대로 둔다.

**2. 스플래시 고정 대기 중 도착한 딥링크를 즉시 처리 (리뷰 반영)**

hasPending을 진입 시점에 한 번만 읽어서, 대기 중에 onNewIntent로 딥링크가
도착해도 delay가 끊기지 않았다. 이동이 유실되지는 않지만 최대
SPLASH_TIMEOUT_MILLIS(2.3초)만큼 늦어진다.

«pending 도착»과 타임아웃을 경쟁시킨다.

  withTimeoutOrNull(SPLASH_TIMEOUT_MILLIS) {
      pendingNavigationStore.pending.filterNotNull().first()
  }

이미 도착해 있으면 first()가 즉시 반환하므로 기존의 «딥링크면 고정 대기
건너뛰기»도 이 한 줄에 포함된다. 유일한 소비자가 사라진 hasPending은 제거했다.

검증: ktlintCheck / assembleDebug / 단위 테스트 통과.
