fix: conditionalSwitch using stale input from previous workflow run

The useMemo for incomingText depended on edges (from useEdges), which
doesn't change when upstream node data changes. On re-runs, the memo
returned stale text and the useEffect overwrote correct execution
results. Replace with a Zustand store selector using
getConnectedInputsPure that recomputes when upstream node data changes.
