refactor(inquirerer): move AI code demo to dev/ai/ folder

- Move aicode.ts and viewport.ts from src/ui/ to dev/ai/
- These files are now demo-only and not bundled with the package
- Update imports in demo-ai-code.ts
- Remove exports from src/ui/index.ts
- Keypress additions remain in src/ as they're useful for other components
