Separation of concerns: merge silent/UI actions & modularize screens.
ProleInstallerBase (actions.py): Created shared base class with 37 deduplicated methods previously duplicated between ProleSilentInstaller and ProleInstaller. Namespace, environment, secret, deployment, port-forward, authority/repair, image, and logging helpers now defined once. Subclasses override _get_input() to bridge their data-access layers.
screens.py -> screens/ package (18 mixin modules): Split 10,234-line monolithic screens.py into focused mixin modules: base, navigation, welcome, dependencies, network, environment, database, cluster, services, security, ollama, supabase, docker, build, packaging, deploy, validate, cfg. __init__.py composes ProleInstaller from all mixins and re-exports has_display(), main() for full backward compatibility.
All 37 tests pass with no regressions.
- Refactored installer UI with updated canvas rendering, sidebar navigation, and footer buttons.
- Enhanced styling for macOS compatibility and consistent design across controls.
- Added Pytest-based unit tests for `screen.py` and `config.py`.
- Expanded dependency catalog with new tools like `tshark` and `pyshark`.
- Improved error tolerance for background rendering and added placeholders for Kerberos configuration.
