* Mangataro
* Refactor: Simplify search payload creation
- Use a custom serializer for search filter parameters.
- Remove redundant `.toJsonString()` calls for each filter.
- Update filter classes to use appropriate data types (Int, Int?, String?) instead of just Strings, improving type safety.
- Change `firstInstanceOrNull` to `firstInstance` for non-nullable filters.
* Refactor: Move deeplink handler
Move the deeplink handler function to a more logical position after the search parsing logic.
* MangaTaro: Implement new search method
- Add a new text search method that uses a different API endpoint. This provides more relevant results but ignores filters.
- Add a filter option to toggle between the new search and the old filter-based search.
- Exclude novels from appearing in search results and manga details.
