Introduce a "UI" architecture module to the core platform, and move the user interaction services to this new module.

This includes:

- Logging and progress services.
- Problem generation services (aka the "problems API").
- User prompting services.
- Build options infrastructure.
- The console and CLI, as a specific implementation of these services.
