Suppport for airgapped installation

[mahabal-org-ind]

I want to run opencode in kubernetes in an airgapped environment, which only has access to my model endpoint. I installed opencode in my docker image using

RUN curl -fsSL https://opencode.ai/install | bash

But when I try to run opencode in my pod after deployment, I get the following error:

> OPENCODE_CONFIG=claude.jsonc opencode run "what is 2+2"

I would love it if there was a config or environment variable which would prevent network access of any kind, except the model API call. Thanks.
