Final wave: complete the 6th edition basic set (69/69 cards)

The hard six: AROUND THE CORNER attaches to any LOS attack and bends
the sight line through one intermediate cell. BLIND victims lurch in
die-rolled directions (bumping a wall costs the movement point, per
the card) and their attacks fly wherever the die says — hitting
whoever stands that way, or dissipating. UGLY drives every opponent
in sight fleeing along shortest paths (breadth-first, die-broken ties)
until they cannot see the caster. ILLUSION WALL is per-player reality:
each opponent rolls 50/50 the first time it matters and the wall is
real for believers forever — believers' views render it as a wall,
the caster and those who saw through it get a ghostly dashed line,
and Dispel Creation banishes it. ROTATE SECTOR turns a sector 90
degrees with every wall, door, wizard, treasure, object, firewall and
alteration turning in place (the home star, being the exact center,
never moves); RELOCATE SECTOR slides a sector anywhere that keeps all
sectors adjacent, reassembling the map and recomputing wraparounds.

Client: modifier attachment (Amplify/Add/Extend/Around The Corner),
two-stage relocate, rotation direction toggle, dashed known-illusions.
Every card in the 6th edition basic deck is now implemented.
81 tests passing.
