chore(sidecar): silence absorbed view-hierarchy poll noise in Android runs

The driver logs an ERROR for every on-device view-hierarchy fetch that the
device-side server cancels or times out while the UI animates. The stability
poll fetches the hierarchy on a sub-second cadence and swallows those throws
to keep polling, so each line is advisory with no effect on the run. Real
failures still reach the runner as gRPC status errors, so nothing is lost.
