/**
 * @startsimpli/ui/workflows — generic workflow-graph foundation.
 *
 * Pure-TS foundation (types, serialization, layout) for the workflow
 * editor/viewer. Isolated behind a dedicated subpath so consumers that do
 * not need @xyflow/react don't pull it in (mirrors gantt / email-editor).
 *
 * Also exports the read-only execution-monitor components (timeline + run
 * viewer), which are plain React + shared @startsimpli/ui primitives.
