Function animatedMove

src/utils/computerUse/executor.ts:274–312

* Port of Cowork's `animateMouseMovement` + `animatedMove`. Ease-out-cubic at * 60fps; distance-proportional duration at 2000 px/sec, capped at 0.5s. When * the sub-gate is off (or distance < ~2 frames), falls through to * `moveAndSettle`. Called only from `drag` for the press→to motion — target

(
  input: Input,
  targetX: number,
  targetY: number,
  mouseAnimationEnabled: boolean,
)

 * intermediate positions (scrollbars, window resizes).
