feat: implement getHiddenBookmarks for private bookmarks

- Added getHiddenBookmarks from applesauce-core to fetch private bookmarks
- Created HiddenBookmarkData interface for proper typing
- Handle both array and object return types from getHiddenBookmarks
- Combine public and private bookmarks in the final result
- Maintain type safety with proper TypeScript interfaces
- All linting and type checking passes
