CLI exits with zero code even when there are errors and no responses

[roobre]

Seems like there's a bug in doggo, where this condition:

https://github.com/mr-karan/doggo/blob/8492ccdc61f097da3a8e5dcb2080e77650af8d2d/cmd/doggo/cli.go#L166-L168

Never evaluates to true, because here:

https://github.com/mr-karan/doggo/blob/8492ccdc61f097da3a8e5dcb2080e77650af8d2d/cmd/doggo/cli.go#L158-L162

An empty response is always appended to responses, making len(responses) always greater than zero.

I can reproduce this by running doggo foo.local @0.0.0.0, and observing responses with a debugger:

Thanks for reporting. Will be fixed in the next release.
