Change the is_resumption field in WorkflowStarted event into reason (vibe-kanban 19ac040e)

Reason should be an enumeration with only one member `resumption` currently.

Please update these part of events:

- Graph / Engine Event (GraphRunStartedEvent)
- Queue event (QueueWorkflowStartedEvent)
- SSE response event (WorkflowStartStreamResponse)

Besides, you should remove the `is_resumption` flag for `node_started` events; including:

- Queue Event (`QueueNodeStartedEvent`)
- SSE Event (`NodeStartStreamResponse`)
- Node event (`NodeRunStartedEvent`)

After finishing the changes above, adjust related tests.
You should run the affected tests and ensure they can pass. (You should use `uv run pytest` to run tests)
