events_create: ValidationError on RemoteRef in EventResult.event.run_completed.eventData.output

[kalyanaramansanthanam]

SDK version: vercel==0.5.8

events_create for a run_completed event raises a ValidationError because the workflow service returns a RemoteRef for event.run_completed.eventData.output, but EventResult (and the underlying WorkflowRun.output schema) is typed as list[bytes] | None.

The request URL includes ?remoteRefBehavior=resolve (set by worlds/vercel.py:288–296), so the SDK is asking the server to dereference, but the server appears to send a RemoteRef object back regardless.
