Pip version - Bind 0.0.0.0

[EULArule]

In the pip version of llmstack, when you run the commands.
llmstack -h OR llmstack --help

There is no helpful output, and instead starts up the server. One thing not documented real well was the way to switch between production and the development server, or if its even possible with the pip packaged version. And how to bind the server to port 0.0.0.0:3000 so anyone is able to access it. And I think these will all be very useful features as it is applicable when you want to share your apps on llmstack with other people not on the same system.

Describe the solution you'd like
I would like a feature that when you do llmstack -h it outputs something like.
Usage llmstack [flags]
--listen [binds server to 0.0.0.0]
--prod [Runs production server]
--dev [Runs development server]
...
...
...

Describe alternatives you've considered
Alternatively I was able to bind the server to 0.0.0.0:3000 by editing the file "~/.llmstack/config" and changing llmstack_port = 3000 -> llmstack_port = "0:3000" and add the line allowed_hosts = "0.0.0.0,localhost,192.168.0.X". Where 192.168.0.x = your local ip. And you can now access it from other machines on the network. It has however caused a bug, that I recently reported has occurred due to this change.
