Duplicating an item drops to the catalog placement flow, which rebuilds the
draft from the asset + transform and never carried node.slots — so the copy
lost every painted slot override. Thread slots through the draft create path:
useDraftNode.create seeds it onto the draft and commit() forwards it to the
final node, the placement coordinator passes it to its lazy wall/ceiling
draft creates, and the item move tool supplies node.slots for both the floor
(direct create) and wall/ceiling (coordinator) duplicate paths.
