Manually start a workflow run

Kick off a run without waiting for an inbound message (useful for testing). Target an existing conversation by `conversationId`, or (WhatsApp only) a phone number via `to` (a conversation is found or created). `text` seeds the run's `lastMessage` variable. The graph must be runnable.

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.
