기존 `PrezelSnackBar.kt`를 `snackbar/PrezelSnackbar.kt`로 이동 및 구조를 변경하고, `SnackbarHostState`와 연동 가능한 컴포넌트들을 추가했습니다.

*   `PrezelSnackbar`: `SnackbarData`를 직접 받도록 변경하고 `PrezelSnackbarDefaults` 객체를 통해 스타일 상수를 관리하도록 수정
*   `PrezelSnackbarHost`: Material3 `SnackbarHost`를 기반으로 하는 커스텀 스낵바 호스트 추가
*   `showPrezelSnackbar`: `leadingIcon`을 포함할 수 있는 `SnackbarHostState` 확장 함수 추가
*   `PrezelSnackbarVisuals`: 커스텀 아이콘 지원을 위한 `SnackbarVisuals` 인터페이스 구현체 추가
*   기타: 파일 경로 이동 및 미리보기(Preview) 코드 최신화 (Ellipsis 제거 및 최소 높이 설정 등)

*   `PrezelSnackbar`에서 하드코딩된 스타일 값들을 `PrezelTheme` 시스템(shapes, spacing)을 사용하도록 변경했습니다.
*   `PrezelSnackbarDefaults` 내 불필요한 상수 및 미사용 import를 제거했습니다.
*   `showPrezelSnackbar` 확장 함수에 `onAction`, `onDismiss` 콜백 파라미터를 추가하고 결과 처리를 구현했습니다.
*   `SnackbarVisuals`에서 `leadingIcon`을 추출하는 내부 유틸리티 함수 `leadingIconOrNull()`을 추가했습니다.
*   미리보기 코드에 `PreviewScaffold`를 적용하여 구조를 개선했습니다.

*   `PrezelSnackbar`에서 하드코딩된 스타일 값들을 `PrezelTheme` 시스템(shapes, spacing)을 사용하도록 변경했습니다.
*   `PrezelSnackbarDefaults` 내 불필요한 상수 및 미사용 import를 제거했습니다.
*   `showPrezelSnackbar` 확장 함수에 `onAction`, `onDismiss` 콜백 파라미터를 추가하고 결과 처리를 구현했습니다.
*   `SnackbarVisuals`에서 `leadingIcon`을 추출하는 내부 유틸리티 함수 `leadingIconOrNull()`을 추가했습니다.
*   미리보기 코드에 `PreviewScaffold`를 적용하여 구조를 개선했습니다.

- `PrezelSnackbar` 내 액션 버튼의 크기를 `SMALL`로 지정하도록 수정했습니다.
- `leadingIconOrNull` 확장 함수의 위치를 `SnackbarHost.kt`에서 `PrezelSnackbar.kt`로 이동하고 가시성을 `private`으로 변경했습니다.
