Safes finally open to keys — and the clockwork stops clawing at the lid

'All LOCK-type cards will work on it' was never wired: openSafes was
reset every turn and filled by nothing. A PICK LOCK or MASTER KEY
aimed at a safe's square (underfoot or beside) now opens it until
turn's end, with its own chronicle line; the dead never-emitted
safeOpened variant and its null humanize go. The automaton — H4EN's
Automaton II spent six turns grabbing at a locked lid saying 'I meant
to do that' — now cracks the box first (key or DISPEL CREATION, which
it held the whole time) and drops unopenable safes from its goals
rather than marching to one forever.
