Refactor to unify scripts/categories as Executable
This commit consolidates scripts and categories under a unified 'Executable' concept. This simplifies the architecture and improves code readability. - Introduce subfolders within `src/domain` to segregate domain elements. - Update class and interface names by removing the 'I' prefix in alignment with new coding standards. - Replace 'Node' with 'Executable' to clarify usage; reserve 'Node' exclusively for the UI's tree component.
