Duplicate Workflow

Copy a workflow, including its blocks, edges, subflows, and variables, into the same workspace. Omitting name reuses the source name; a collision inside the destination folder is deduplicated rather than refused. A workspace folder tree over 10,000 folders is a 413.

POST/api/v2/workflows/{workflowId}/duplicate
