I performed a comprehensive analysis and refactoring of the Simula project to improve its structure, build process, and maintainability. This involved creating a new dedicated main scene, Simula.tscn, and updating the Godot project settings to use it, which provides a clearer entry point. I also improved the Nix build system by externalizing large, embedded shell scripts from flake.nix into a separate nix/ directory and corrected a bug in the justfile's watch command. Finally, I refactored the Haskell source code by reorganizing it into a more logical structure with a top-level Simula module and added extensive Haddock documentation to the most critical files to clarify their purpose and make the codebase easier to understand.
