Pipe: remove context.WithCancel that caused premature ctx.Done() before the second pipeHalf could return its error. Replace with a completed counter that drains both errors even on cancellation. Transport: increase error channel buffer from 1 to 2 to prevent goroutine leak when both CopyBuffer goroutines complete.
