Implement a new clearance mode switching feature, allowing users to toggle between 'foundation' and 'corp' themes. This includes defining new themes with distinct visual styles, updating state management for persistence, and adding a `switchClearance` function with associated UI feedback and animations. New desktop applications are also introduced for the 'foundation' mode.
