NEON-29: Faster vertical descent — accel multiplier + peel until feet arrive 

Apply PLAYER_VERTICAL_ACCEL_MULTIPLIER (~2.45×) to walk-airborne gravity,
ledge peel integration, and idle-airborne gravity for snappier falls.

Peel used to clear when goal.y >= feet_y - DESCEND_GOAL_Y_MARGIN, which
stopped peeling ~6 cm above the click surface while XZ was already at the
destination — use vertical_arrival_error <= VERT_ARRIVE_EPS instead, with
a small guard when the goal is clearly above the feet (climb).
