fix(android): keep panel overscroll inside inverted timelines

Android forwards a nested panel’s unconsumed scroll and fling to its inverted parent, moving the timeline in the opposite visual direction. Keep that motion inside the panel while preserving ordinary parent scrolling and nested-scroll registration.

+Nested panels also keep their edge overshoot and unconsumed flings inside the panel instead of

+inside the panel are preserved. Run the native selection and nested-scroll regressions after prebuild:

 Register this package before React Native's core package through its Expo config plugin. Normal
 Android builds use the prebuilt `react-android` library, so patching Java under `node_modules` does
 not change the shipped scroll view. Keep this behavior in the app's compiled native module.
