Major CLI Update

pengy-cli relied too heavily on the gui for configuration. Added more slash commands to allow it to work fine in headless environments where the gui will not be available to do initial configuration.

Maybe test things this time

CLI was broken on fresh install because of a packaging issue with rich library. Fixed it and added some tests for the future.

Bugfix release

Issues with the indicator display, missing imports on the cli tool, proper table and external image render and the cli one shot mode adding to the chat history when it should not.

1.0

Pengy is useful enough for everyday use.
