feat(installer): add internet wizard, localization, and software profiles

- Add interactive internet connectivity check with nmtui wizard
- Implement searchable timezone selection using gum filter
- Add keyboard layout selection with custom input fallback
- Implement multi-select software profiles (Dev, Gaming, Media)
- Generate clean downstream scaffolding with system.nix/home.nix stubs
