* Fixed: `ImportBookmarkTest` which was failing on CI.
* Refactored UI and unit test cases according to the new codebase.
* Fixed: Selecting a ZIM file would select all ZIM files displayed on the Local Library screen.
* Fixed: `network result & language db results activate a combined network + db result`, `library marks files over 4GB as can't download if file system state says to` and `books found on filesystem are filtered by books already in db`, which sometimes fails on the CI.
* Fixed: Saved books in the library were not appearing on the Local Library screen.
* Fixed: Opening a ZIM file via the download notification was not working.
* Fixed: Selecting a ZIM file would select all ZIM files displayed on the Local Library screen.
* Improved: Migration logic now properly migrates books that were stored in the file system before introducing `ZimReaderSource`.
* Removed books from `library.xml` if they no longer have any associated bookmarks, as keeping them is unnecessary and wastes resources and memory, while also increasing the time needed to load the library from storage.
* Fixed: The downloading online library progress was showing incorrect.
* Refactored the all unit test cases according to the new changes.
* Fixed: `Online Books` were showing incorrect book sizes. The OPDS stream now provides sizes in bytes instead of kilobytes, so the code has been updated accordingly.
* Added the `io.coil-kt.coil3:coil-compose` library to load favicons for online books, as OPDS now returns favicon URLs instead of Base64-encoded strings.
* Since favicons are no longer provided in Base64 format when downloading ZIM files, we now extract the favicon from the Archive using libkiwix after the download completes. This allows us to display it locally on various screens such as the library, Wi-Fi hotspot, notes, history, and more.
* Cached the `LibkiwixBook` instance to avoid recreating it multiple times when adding or removing bookmarks.
* Created `LibkiwixBook` to wrap the `Book` class from `libkiwix`, allowing us to set custom values from the database and manage books received from the `OPDS` stream. This wrapper is necessary because the original Book class does not provide setters. We'll use `LibkiwixBook` throughout the codebase.
* Refactored the codebase to replace `LibraryNetworkEntity.Book` with `LibkiwixBook`.
* Removed the BaseDelegateAdapter and its subclasses, as RecyclerView is no longer used in the codebase.
* Fixed: CustomApps was crashing when opening the settings screen.
* Fixed: StorageList was not appearing on the settings screen.

* Refactored the functionalities of `SearchFragment` according to compose UI.
* Removed the unused code from project.
* Updated the logic to hide the top progress bar when updating the library items while applying filters.
* Refactored all unit test cases to properly support coroutines.
* Fixed: Download progress of the online library was not displayed when navigating away from the fragment and returning while the download was still in progress.
* Fixed: Both the SwipeRefreshIndicator and the progress bar were shown simultaneously during the initial download of the online library.
* Improved: The logic for hiding the SwipeRefreshIndicator. It now automatically hides when the progress bar (with visible progress) is displayed.
* Improved: Handling of library re-downloads upon network state changes.
* Fixed: The progressBar was showing when we searching for books.
* Fixed: Compilation errors in unit test cases.
* Fixed: Selected language filter was not being applied to the online library.
* Fixed: Unnecessary UI recomposition.
* Improved code readability and resolved related lint errors.
* Fixed: "Allow downloading content via mobile network?" dialog was not displaying correctly.
* Fixed: SwipeRefreshing was not working when the "Swipe Down for Library" message was shown.
* Improved: Previously, the online library would re-download every time the fragment was launched or brought to the foreground (e.g., when navigating back from another screen). This behavior has been changed to use coroutines. The library now downloads only once initially, and subsequent downloads only occur when the user manually refreshes the library. This helps reduce unnecessary data usage and network calls.
* Refactored the child viewModels (BookmarkViewModel, HistoryViewModel, and NotesViewModel) to use coroutines.
* Refactored all DAO classes to use coroutines instead of RxJava.
* Refactored all related code to align with coroutines.
* The issue was caused by using `CoroutineScope(Dispatchers.Main)` while our flow directly accessed the `uuid` of the ZIM file from the `ZimFileReader` object. When the fragment was switched to another screen, the `ZimFileReader` object got disposed. However, the `webViewProgressChanged` method would still trigger, initiating the flow to check if the current page was bookmarked. Since the `ZimFileReader` was already disposed, this resulted in a crash.
* We fixed this by using the viewLifecycleOwner.lifecycleScope so that the job is automatically cancelled when the fragment is destroyed. Additionally, we now retrieve the uuid once at the beginning and reuse it in the flow, avoiding repeated access to the disposed ZimFileReader.
* Improved the `testBookmarks` test case. Sometimes this test failed to find the "OPEN" button of the `Snackbar` because the `Snackbar` was automatically dismissed before `Espresso` could validate the view. This timing issue occasionally caused the test to fail. We've improved the test to properly verify whether the bookmark is saved, avoiding such situations.
* Improved the `DownloadTest`, which sometimes failed on CI.
* Refactored all `RxJava` code in `SharedPreferenceUtil` to coroutines.
* Refactored `RxJava` code to coroutines in `Fat32Checker`.
* Refactored `RxJava` code to coroutines in `DarkModeConfig`.
* Refactored all related code of these classes accordingly.
* Updated unit test cases to work with coroutines.
* Refactored the IP address polling logic using coroutine Flow. Now the IP check runs on the IO thread and the result is pushed to the main thread, because our callbacks need to work on the main thread. Also, this whole operation will automatically cancel if the user switches the screen or if the given coroutine scope gets cancelled, since the scope is lifecycle-aware. This helps to avoid using extra resources unnecessarily.
* Added clear and concise method-level comments to improve code readability and help others easily understand the purpose and behavior of each method.
* Removed duplicate method in `DownloadRoomDao` for fetching all downloads.
* Refactored `DownloadManagerMonitor` to use `Coroutines` instead of `RxJava`.
* Improved coroutine usage in `DownloadMonitorService`.
* Updated `LanguageViewModel` to use `Coroutine Flows` instead of `RxJava`.
* Refactored `NewLanguagesDao` to expose Coroutine Flows instead of `RxJava` observables.
* Updated `SaveLanguagesAndFinish` to use coroutines instead of `RxJava`.
* Created a `FlowExtension` utility class to add custom flow-related extensions. In this PR, added the `collectSideEffectWithActivity` extension function, which allows collecting `SideEffects` and handling them with the current Activity in a Compose UI. This also moved the `SideEffect` collection from the Fragment layer to the Compose screen, improving separation of concerns.
* Refactored the unit test cases according to this change.
* Created an `asFlow` extension function to convert ObjectBox queries into coroutine Flow, enabling easier migration to coroutine-based flows in future tasks.
