* if we run 2 servers at once (if in `app` server is already running then we can not run the server on the `custom` module since we can not run 2 servers on the same IP.) So for this, we have improved our code to show the proper error message so the user will know why the server is not running.
* Moved wifi hotspot related files to core module to use hotspot functionality in both app and custom module.
* Moved permission in core manifest to access them in both modules.
* Removed some unnecessary files which is now no longer in use.
* Added logging for cases where the `ZimFileReader` failed to find an entry, failed to load an asset, and more.
* Significantly improved the "load more" functionality: Now, if the user is near the end of the list, we start loading new search results. This enhancement enhances the user experience by reducing wait times for new search results.
* Added references in the `KiwixServer` class to help developers understand why we are keeping the library object.
* Implemented test cases to thoroughly test the `getMimeTypeFromUrl()` function in the ZimFileReader class.
* Enhanced the search functionality by consolidating the use of a single viewModelScope instead of multiple coroutines, reducing the potential for future issues.
* With the integration of libkiwix12, we now receive full results based on the search term. Previously, we were loading the entire list, but we have now implemented pagination to enhance the search functionality.
* The libkiwix provides us with a Search object, which enables us to obtain the suggestion list using start and end indices. Consequently, we have modified our `ZimSearchResultGenerator` code to return the `Search` object instead of a list.
* To accommodate the changes, we have updated the return type of `SearchResultGenerator` to a nullable Search. This change is necessary because we initialize the `SearchState` when the search is initialized in `SearchViewModel`, and initially, we do not have the Search object available. The nullable return type allows us to pass the Search object when it becomes available.
* Previously we can only open zim files from `USB-OTG` in android 10 and below devices, because `context.getExternalFilesDirs("")` does not provide the USB path in android 10 and above devices for security reasons. There is no direct way to access the USB-OTG on these devices, but USB-OTG are mounted under the `/mnt/media_rw` directory, so now we are directly using this to open zim files from USB drive for android 10 and above devices.
