Open the webui when Dim server is launched

[Valerian G.]

When the dim binary is ran, once the webserver is initialized, it should open a browser window unless otherwise specified via a flag.

👎 there should be a --open option that would do this, and some very explicit output to the console that says "the webserver is running and it accessable via this link: https://....."

Several users have complained that it is not obvious when dim is running and what to do once the app is running. In an ideal world we would bundle the web-server with a GUI but for now I think opening a browser window by default is ideal.

yeah fair enough

Hi, I'd love to help with this issue!
Do you have any thoughts on how you'd like to see it implemented?
