- DriverInstanceSpec carries ClusterId from the deployment artifact;
DriverHostActor threads the real cluster identity into
DriverInstanceActor instead of the local NodeId. Old pre-PR
artifacts without a ClusterId field fall back to the NodeId so
in-flight deployments keep working.
- DriverHostActor.ChildEntry holds the full DriverInstanceSpec
(was only carrying DriverType + LastConfigJson). Restart respawns
preserve RowId, Name, Enabled, ClusterId — no placeholder values.
- Drop the unnecessary _faultLock on DriverInstanceActor — every
read/write site runs inside an Akka message handler which is
single-threaded per actor instance.
- DriverStatusPanel.DisposeAsync awaits Timer.DisposeAsync so an
in-flight 5s tick can't invoke StateHasChanged on a component
whose hub has already been torn down.
