Description

Environment variables are scattered around the docs portal.
There is already a hidden section within Reference >> CLI reference.
Make it a first class citizen so that we have clarity on what can be used where.

Issue Type

Missing documentation

Suggested Fix

The docs for Hermes Agent is very helpful:
https://hermes-agent.nousresearch.com/docs/reference/environment-variables#interface

I suggest we send an agent to collect everything which is already mentioned so that it can build a draft table that could be reviewed.
