feat: Enhance Welcome Screen and Menu Structure in EditorManager

- Integrated a new `WelcomeScreen` class for a modernized user experience, featuring callbacks for opening ROMs, creating new projects, and opening existing projects.
- Updated the menu structure to include new items for message and music editors, as well as an AI Agent menu for collaboration features.
- Added functionality for hosting and joining collaboration sessions, along with options for network settings and session management.
- Improved the welcome screen display logic to handle recent projects and user interactions more effectively.
