Feature Request

I'm using dx serve with Claude Code, but it's having trouble managing the dx serve process itself so I'm running dx serve in another terminal. This works reasonably well, except that sometimes when mid-edit the serve loop gets into a bad state and I need to tab over and hit r to force a rebuild.

I was hoping that CC could trigger that action itself by sending a SIGHUP signal to dx (e.g. by using pkill -HUP dx but currently that actually just kills dx serve.

Implement Suggestion

As far as prior art, nginx is a good example where SIGHUP forces a reload of nginx.conf. As a first pass, having SIGHUP behave just like pressing r seems like a good start.
