fix: ensure auto-routed prompts retain correct individual item text

The PromptNode text-sync effect can overwrite the per-item text set by
addNode before edge arrayItemIndex data is fully settled. Add a deferred
fix-up pass (setTimeout 0) that re-applies the correct text after React
effects have run.
