PageContext.treeToState, apply-ai-response.buildNodeTree, and the dead
serializeTreeForCraft each re-implemented the same ColumnLayout-linkedNodes +
SHELL_INNER walk and had drifted (buildNodeTree gained guards the others
lacked). Move sanitizeAiTree (resolvedName allowlist + id/ROOT repair) here
too and add flattenTreeForCraft, the shared structural walk (linkedNodes,
SHELL_INNER wrapping, style:[]->{} normalization) both real callers will
consolidate onto.

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.

Craft.js duplicate (ContextMenu + keyboard shortcut) and paste were reusing
the original node's toNodeTree() output verbatim, so addNodeTree() inserted
duplicate node ids into the editor tree. Added regenerateTreeIds() which
deep-clones a NodeTree and remaps rootNodeId, node map keys, node.id,
internal node.data.parent, node.data.nodes, and node.data.linkedNodes via
Craft.js's own getRandomId(). Also fixed pasteNode to insert as a sibling
of the right-clicked node (using its parent) instead of using a leaf node
as the new parent, which previously threw.
