shadowdao 1a88baa95d fix(builder): deep-clone node data on id regeneration to avoid shared props
regenerateTreeIds shallow-copied each node's data, leaving data.props (and
data.custom) as the same object reference between the original node and its
duplicate/pasted copy. Craft.js's setProp mutates data.props in place, so
editing the duplicate's props silently mutated the original too. Deep-clone
data via structuredClone before applying id remaps so no mutable sub-object
is shared between original and regenerated nodes.
