Hi! I use a custom docker image to build and run cairo files. Today, cairo-run ... --tracer uses localhost to host the tracer ui. This unfortunately means that I cannot properly forward traffic from my host to the container. A simple fix would be to replace localhost with 0.0.0.0 at this line

However, maybe we can generalize and allow the user to choose the ip and port on which the tracer ui is hosted. For example, maybe

cairo-run ... --tracer --tracer-ip 0.0.0.0 --tracer-port 8101
