The screensaver used to return through .renderArrows (reloading the font,
re-clearing/re-arming OAM+LCDC -- all pointless when arrows are hidden) plus an
idle DelayFrame between every page, giving a ~1-frame hitch each screen. Add
.afterMove: in saver mode it skips all that and dispatches the next direction
immediately, so in-map pages chain back-to-back and the camera scrolls
continuously. Manual EXPLORE still redraws its arrows as before.
(Map-boundary crossings still briefly freeze while LoadMapData reloads the
neighbour -- inherent to the full map load; a same-tileset fast path would be a
larger, riskier change.)
