Single lifecycle entry surfaced by the in-process GraphRunStream.lifecycle projection. Combines the CDDL LifecycleData payload with the namespace it applies to so consumers can filter or correlate without dipping into raw ProtocolEvents.

Resolves to an error message string if ToolCallStream.status is "error", otherwise undefined.

Wall-clock timestamp (milliseconds) of the emission.
