Rev 19: breaching the rim opens a new warp across the maze

Destroying a wall on the board's outer edge used to leave a one-sided
hole into nothing. The table's physics prevail: the outer rim wraps,
so the breach goes clean through — the opposite perimeter wall in the
same row or column crumbles too (collapse damage and all), and a new
warp pair opens between the two edges, shimmering at both mouths.
Rev-gated: stored games hold one-sided breaches and replay so. Sector
moves recompute the wraparounds and forget improvised openings, as
the maze's own reshaping always has.
