Eric's ask. duplicate-unit clones the STRUCTURE — openings with their
sizes, zones, and descriptions, under fresh ids and the first free
"<name> 2"-style name — never the game assignments. And because a
copy immediately wants a real name, units gained rename: opening ids
are stable through it so locations and export URLs never notice, and
a rename-only edit no longer risks wiping the description (the body
field learned the None-means-leave-alone convention). Tests pin the
disjoint ids, the empty copy, the numbering past taken names, and
the wipe-nothing rename.
