List a workflow's version history

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

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 not be `active`: pause it first, then restore. The returned workflow carries `restoredFromVersion` so the UI can surface which version was rolled back to.
