Default to non-multithreaded until UI toggle support

Patching large applications (e.g. TikTok) on Android with multithreading simply doesn't work on multicore devices where the amount of memory given to the manager (regardless of the system RAM) is not sufficient.

It's more important that patching succeeds for all available use cases than for only some patching to succeed with faster performance. A UI option can be added later, but the multithreading option should be opt-out by default rather than opt-in.
