issue: #45728 pr: #45730 When mixcoord is in standby mode and shutdown is triggered, the ProcessActiveStandBy goroutine may panic if context cancellation occurs. This happens because the error handling didn't check for context.Canceled errors before panicking. Changes: - Add context cancellation check in mix_coord Register() before panic - Check s.ctx.Err() == context.Canceled and gracefully exit - Remove unused ForceActiveStandby() function from session_util This ensures standby mixcoord can shutdown gracefully without panic when context is cancelled during the standby process.
