Hermes Wingtips #56: switching models from anywhere

`hermes model` opens an interactive picker, so it refuses to run through a pipe, a script, or another agent's terminal tool.

the fix is that you never needed the picker. in any chat, on any platform:

/model grok-4 --provider x-ai --global

`--global` persists it to config.yaml and switches the running session in the same move.

`--once` is the sibling: it switches for a single turn and restores the previous model afterward, even on an error.
