Not that I particularly think there's anything wrong with signaldctl, but for other apps that employ a daemon/control model, I've always found <service_name>d and <service_name>-cli combo to be good naming scheme.

So signald and signal-cli in this case.

well "signal-cli" is already in use by https://github.com/AsamK/signal-cli (which signald is a fork of)
