refactor: implement component-based architecture for enhanced maintainability

- Reorganize directory structure into core/, features/, and themes/ - Colocate application Nix logic, configs, scripts, and theme overrides - Implement 'Inversion of Control' for theming: apps now pull theme-specific layouts - Update flake.nix and shared library paths to match the new structure - Document the new Feature-Centric architecture in README.md
