Change setupRecordingProxy to return func() error instead of swallowing errors internally, making it consistent with setupFakeProxy. Use a named return in runOrExec so deferred cleanup errors are propagated when no prior error occurred. Fixes docker#1691 Assisted-By: cagent

Add a done channel to ensure the background goroutine that closes stdin exits cleanly when monitorStdin returns, not only when the context is cancelled. This prevents the goroutine from leaking if stdin closes before context cancellation. Fixes docker#1664 Assisted-By: cagent
