Lataa Strata Manager 0.2.47

- Adding an engine argument no longer writes it twice (#226): when the config already had custom arguments (user_args), one click on "Add argument" in the full engine argument list wrote the same option twice. It now adds one copy. A single-use option that is already in the list is updated in place (the button reads "Update item N" and the row is highlighted); repeatable options such as --control-vector and unknown options are still appended.
- Model preparation says what differs from the current settings (#225): when "My models" already has the same model and this preparation differs in model name, weight files, context or image input, the task used to say only that the managed snapshot differed. The task now shows "Needs your choice" instead of "Completed", lists each difference with the current and prepared values (for example context 160K now, 128K this time), and offers Keep current settings, Change settings and Detect again.
