[bug] pygmy status prints a special character

[sonnykt]

Describe the bug
On MacOS/M3, the command pygmy status prints a special character at the front of the SSH keys check:

That special character makes the whole output not text-only and may cause errors if pipelined to other commands such as tr:

$ pygmy status | tr -d '\000' 
[*] amazeeio-mailhog: Running as container amazeeio-mailhog
[*] amazeeio-haproxy: Running as container amazeeio-haproxy
[*] amazeeio-dnsmasq: Running as container amazeeio-dnsmasq
[*] amazeeio-ssh-agent: Running as container amazeeio-ssh-agent
[*] Resolv MacOS Resolver is properly connected
tr: Illegal byte sequence

The hexa code for that special character is \x01000000000000.

If I run the command ssh-add -l directly in the amazeeio-ssh-agent container, there is no special character in the output.

@fubarhouse thanks for your work. The new flag --json really helps although I am still seeing the special character from pygmy status on Pygmy 0.13.1.

[fubarhouse]

When I last looked at it, there was an anomoly which I just couldn't eliminate...
It has been long enough, so maybe I can try again.

[sonnykt]

This issue is still happening with 0.13.2. However, I notice that the issue only occurs when I have more than one key.
