tommulkins/hermes-gateway-selector ? reverse-engineered prompt

Build me a small shell tool for Hermes that lets me switch between my local agent and a few remote gateways right from the terminal.

When I type hermes with no extra arguments, I want an interactive picker that shows my saved gateways and lets me choose one. If I run normal commands like hermes update or hermes setup, those should just go straight to the real Hermes binary without any prompt. If I haven’t added any gateways yet, it should just open Hermes normally.

I’d like it to work in both bash and zsh, with an install command that sets up the shell wrapper for me and an uninstall that cleanly removes it. Please add commands to list gateways, add one by name and URL, remove one, and open a gateway directly. Store the gateway list locally in my home folder, and support remote connections, including the password based setup when needed. If you need to check current Hermes docs or connection details, look them up online.
