Automatons wield Pass Through Wall and deny roads with terrain

Pass Through Wall joins the march: the bot banks a crossing when stepping
through one wall beats the walk by 4+ steps (or no road exists), walks to
the chosen wall, and spends the charge stepping through. passWallCharges
is now in PlayerPublicView — the cast is public at a physical table.

Path denial for guardGold tiers: when an enemy carries the bot's treasure
toward home, or closes on its gold on the floor, the bot reconstructs the
threat's shortest path and prices every corridor line and empty square on
it; CREATE WALL, FILL SQUARE WITH STONE, or THORNBUSH lands wherever the
detour costs the enemy 3+ steps, legality mirrored from the engine
(sighted, empty, off homes and warp tokens).

All five cards leave the bottom discard tier (2 -> 6).
