}List a workflow's version history GET
Returns the snapshot history. A new version is recorded automatically before every PATCH to `nodes` / `edges` / `entryNodeId`, and explicitly when a previous version is restored. Lightweight list — call `getWorkflowVersion` for the full snapshot graph.
Restore a workflow version POST
Replace the current graph with the named version's snapshot. Before the swap, the current graph is itself snapshotted as a new version, so a restore is reversible. The workflow must be in `draft` or `paused` status (same gate as a normal graph edit). The returned workflow carries `restoredFromVersion` so the UI can surface which version was rolled back to.
