Creatures walk open doorways, and the interruption gets its fanfare

Player movement asked the full question of a door — removed, keyed
this turn, or held — while creature movement only saw "door" and
refused, so a skeleton balked at a doorway its master had unlocked
for good. One doorIsOpen() now answers for both, and an open doorway
costs a wraith none of its wall passes.

And the interruption window earns the modal it deserved: "The maze
holds its breath" — the card shown, the instruction plain, dismissed
with "Seize it". No more hunting the rail for a slip while time
stands parted.
