TapHintPointer class
Non-blocking animated hand that shows the player where to tap or swipe
(FEAT-131). Complements SpotlightOverlay/TutorialSequence, which dim
and explain but do not demonstrate the gesture.
Locate the hint with exactly one of targetKey (center of an already
laid-out widget, same model as SpotlightOverlay) or position (a
global-coordinate point, e.g. a cell inside a Flame game). For
TapHintGesture.swipe, swipeTo is the global end point.
Mount it inside a Stack that covers the same area as the screen (a
Positioned.fill sibling, like SpotlightOverlay). It never intercepts
touches. The caller owns visible; Reduce Motion shows a static pointer.
