1. Update Cmd IO handling …

   Update `Cmd.Wait` to return a known error value if it times out waiting
   on IO copy after the command exits (and update `TestCmdStuckIo` to check
   for that error).
   Prior, the test checked for an `io.ErrClosedPipe`, which:
   1. is not the best indicator that IO is stuck; and
   2. is now ignored as an error value raised during IO relay.
   
   Update `stuckIOProcess` logic in `cmd_test.go` to mirror logic in
   `interal/exec.Exec`, using `os.Pipe` for std io that returns an `io.EOF`
   (instead of `io.Pipe`, which does not).
