currentQuestIndexPath의 빈 IndexPath 반환을 제거하십시오.

buildQuestIndexMap은 steps에 포함된 퀘스트만 캐시에 추가합니다. currentStep에 해당하는 퀘스트가 없으면 currentQuestIndexPath가 빈 IndexPath를 반환합니다. 이후 QuestCheckViewController.scrollToStep()이 section을 읽기 전에 실패하므로 앱이 종료될 수 있습니다. IndexPath?를 반환하고 scrollToStep() 및 타이머 갱신 호출부에서 캐시 누락을 먼저 가드하십시오.

In
`@ByeBoo-iOS/ByeBoo-iOS/Presentation/Feature/Quest/ViewModel/ProgressingQuestsViewModel.swift`
at line 153, Update currentQuestIndexPath to return IndexPath? rather than a
default empty IndexPath when currentStep is absent from questIndexMap. Guard the
missing-cache case before reading section in
QuestCheckViewController.scrollToStep() and before timer refresh call sites,
while preserving existing behavior for valid index paths.
