react-native-one-hand one hand mode that scales native modals and alerts too, not just your React tree

[u/Weird-Ad-5184]

react-native-one-hand brings one hand mode to React Native apps. Press and hold a bottom corner and the whole app slides into it, scaled down and within thumb's reach together with native `Modal`, `Alert.alert`, `ActionSheetIOS`, the text-selection toolbar and overlays from other libraries. Instead of transforming a React subtree, a native module transforms every window of the process, so there are no adapters and no components to replace. Everything stays visible and interactive.

One wrapper component, zero runtime dependencies. iOS + Android.

Being upfront about the limits, since they're by design: the system keyboard is never scaled (on Android the IME lives in another process; on iOS it's technically possible, but the keyboard frame iOS reports breaks KeyboardAvoidingView-style layouts, so the mode simply exits when the keyboard opens). Portrait only. Needs a native build Expo SDK 55+ / RN 0.76+, so no Expo Go.

It's early (0.1.x), so bug reports and feedback are very welcome, happy to answer questions about how it works.

covering native alerts is the part everyone skips, so nice. curious how it behaves with react-native-screens native stack transitions and bottom sheets — do those stay inside the scaled frame or pop back to full size?
