Lifecycle warnings now recompute client-side from the live graph for
editable workflows, so the banner reflects edits immediately instead of
waiting for a save round-trip. The two deterministically fixable codes gain
one-click fixes in the banner (all view modes):
- missing-merge-region inserts a Merge boundary in front of end;
- missing-completion-summary inserts the canonical completion-summary node
(config from @fusion/core's completionSummaryNode) upstream of the merge
region when one exists, else in front of end.
"Fix all" on the collapsed summary line applies both in order, producing
start → summary → merge → end on a fresh workflow in one click. The other
three codes are structural judgment calls and stay manual.
analyzeWorkflowLifecycle + completionSummaryNode are pure and now re-export
through core's browser-safe types.ts alias entry.
