Key Improvements and Features

Android 16 Support

• Upgraded compileSdk and targetSdk to API 36 (Android 16).

Multi-Page Filter Accumulation

• Fixed an issue where selecting specific media formats (Images, GIFs, or Videos) alongside query tags returned only 2 to 4 results per page.
• Implemented smart multi-page accumulation: the client iteratively fetches subsequent pages until a complete batch of items matching the requested type is gathered.
• Added native tag injection (animated, video, -video -animated) for Gelbooru, Rule34, and Realbooru.
• Improved Realbooru parser to properly distinguish GIF animations from WebM and MP4 video streams.

Automatic Cache Management

• The app now automatically cleans up temporary browsing cache (cached images, cached video chunks, and temporary update APKs) on application startup and exit.
• Favorites storage and Room database remain strictly isolated in persistent internal storage and are never deleted during cache cleanups.
• Removed the manual cache clearing action from Settings as cache management is now fully automated.

Internationalization

• Added a dedicated bottom sheet for switching application languages.
• Added full UI localization for Japanese, Chinese, Korean, and Arabic (closes Issue #2).

UI Polish and Animations

• Unified bottom sheet drag handles across all dialogs (Favorites filter, Explore filter, and Update dialogs) to the standard Material 3 style.
• Smoother dismiss animations across bottom sheets using spring physics via sheetState.hide().
• Replaced popup dialogs for clearing tag blacklists and deleting custom sources with spring-animated confirmation buttons.
• Stabilized the "Check for Updates" row in Settings to prevent layout jitter while checking.
