feat(editor): add hex editor and AI agent functionalities to MenuOrchestrator

- Implemented methods in EditorManager to show the hex editor, AI agent, and chat history, enhancing the editor's capabilities.
- Updated MenuOrchestrator to include new menu items for accessing the hex editor, AI agent, chat history, and other UI elements.
- Improved user interaction by providing quick access to essential features through keyboard shortcuts.

Benefits:
- Streamlines the user experience by integrating additional editor functionalities.
- Enhances the overall architecture by clearly defining roles for UI and editor operations within the MenuOrchestrator.
