* fix: tuist generate가 되지않는 현상 해결

Feature프로젝트에 Sources, Resources, Tests 폴더가 형성되지 않아 발생하는 버그를 수정하였습니다.

* chore: APP단 Coordinator관련 파일 추가 및 폴더링

* feat: AppCoordinator 구성

* feat: TabBarCoordinator 구현

예제

* build: Coordinator 필수 구성요소 모듈화

* chrow: 리뷰 적용

앱코디네이터에서 탭바코디네이터 자식 추가, 탭바 코디네이터 selectedImage 작성
