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.
