Failed to cancel task

Error message

Failed to cancel task

What it means

The QECoreBridge task's cancel() propagated an exception from the underlying taskService (task already terminal, connection lost, or unknown task). The catch logs the task id and wraps the failure in QECoreError so callers see a uniform bridge-level cancel failure.
