* fix(tui): fix model selection and enforce unique model_name, also fix model form button highlight

* feat(tui): add footer view with navigation instructions and update menu structure

* fix(tui): update model selection labels for clarity and consistency

* refactor(tui): remove unused rootChannelDescription function

* refactor(tui): simplify rootModelDescription and remove unused 'q' event handling in channel menu
