Fix intermittent Android crash by upgrading Reanimated to 4.3.1

Reanimated 4.1.x crashes on Android with a NullPointerException in
ViewGroup.dispatchDraw (ReactViewGroup.dispatchDraw) — a child view is
null mid-draw because Reanimated commits a ShadowTree change during the
Android draw pass, mutating the view hierarchy while it's being painted.
Fixed upstream in 4.3.0 (software-mansion/react-native-reanimated#9072).

4.3.x requires react-native-worklets 0.8.x, so worklets moves 0.5.1 ->
0.8.3 in lockstep. react-native is pinned to exact 0.81.5 so the
re-resolve can't pull 0.81.6 (which needs react ^19.1.4, conflicting with
the react 19.1.0 override), and reanimated/worklets are added to root
overrides to force a single version across the tree — two copies of the
worklets runtime throw a version-mismatch at startup.
