Show HN: iOS-style "select text on any image" OCR for de-googled Android

On iPhone and Pixel you can select text in any image like it's real text. On GrapheneOS there was no good equivalent, and I really missed it. TextGrab does that: screenshot → quick settings tile → select and copy, all on-device with no Google services and no internet permission. Built with Fable 5 in an afternoon.
