feat: Add Clean Build feature to find and delete build folders

This commit introduces a new "Clean Build" feature, allowing users to scan for and delete `build` directories within their projects to free up disk space.

The feature includes a dedicated screen with the following functionalities:
*   Browsing for a root project directory (e.g., `AndroidStudioProjects`).
*   Scanning the selected directory to identify Gradle projects and their `build` folders.
*   Displaying a detailed, hierarchical view of projects and their modules, along with the size of each `build` folder.
*   Functionality to select/deselect all, expand/collapse all, and individually select projects or modules for deletion.
*   A floating action button to initiate the deletion process, showing the number of selected folders and the total space that will be freed.
*   Confirmation and result dialogs to ensure a safe and clear user experience.

### Key Changes:

*   **`composeApp/src/jvmMain/kotlin/com/meet/dev/analyzer/presentation/screen/cleanbuild`**: Added a new screen package containing the UI (`CleanBuildScreen.kt`), ViewModel (`CleanBuildViewModel.kt`), UI state (`CleanBuildUiState.kt`), and user intents (`CleanBuildIntent.kt`).
*   **`composeApp/src/jvmMain/kotlin/com/meet/dev/analyzer/data`**:
    *   Created `CleanBuildRepository` and its implementation to handle the logic for scanning projects and deleting folders.
    *   Defined new data models `ProjectBuildInfo` and `ModuleBuild` for the feature.
*   **`composeApp/src/jvmMain/kotlin/com/meet/dev/analyzer/di`**: Updated `RepositoryModule.kt` and `ViewModule.kt` to provide dependencies for the new feature.
*   **`composeApp/src/jvmMain/kotlin/com/meet/dev/analyzer/presentation/navigation`**:
    *   Integrated the "Clean Build" screen into the app's navigation graph (`AppNavigation.kt`, `AppRoute.kt`).
    *   Added a new "Clean Build" item to the main navigation rail (`NavigationItem.kt`).
*   **`composeApp/src/jvmMain/kotlin/com/meet/dev/analyzer/core/utility/Utils.kt`**: Added a `formatElapsedTime` utility function.
