Rev 7: sight passes only through the aisle warps

The cards settle what the morning's feature got wrong. DIMENSIONAL
WARP: "There is no L.O.S. through the warp." The AUTO WARP: "for all
purposes, treat the connected board edges as though they are
adjacent" — an explicit grant, for edges that physically meet at a
corner. The lettered wraparounds get no grant at all: their rule is
about walking. So the pattern is that warps carry movement, not
sight, unless the text says otherwise — and only the aisle corners
say otherwise.

Warps now carry an aisle flag (the 3-player AUTO WARP and the
5-player corner arcs); hasWarpLineOfSight honors only those, with
the adjacency geometry — diagonals through the corner mouth —
unchanged from this morning where it rightfully applies. Games begun
before rev 7 keep the wider sight their logged commands were
validated against, via a legacy flag boardView stamps from the
game's rules revision. Tests pin all three states: lettered mouths
see nothing, aisle mouths see the corner fan, legacy games see
everything they used to.
