feat: Revamp Window Management and UI Components for macOS App

- Updated `SpacedriveApp` to implement multiple window groups, including a main companion window, browser window, icon showcase, and inspector, each with custom title bars and shared state management.
- Introduced `NativeTrafficLights` and `CustomTitleBar` components to enhance window appearance and functionality, integrating native macOS traffic lights seamlessly.
- Refactored `AppDelegate` to initialize app state and manage window configurations based on development settings.
- Enhanced `SharedAppState` to support dynamic window opening based on user preferences and development configurations.
- Added new `BrowserView` and associated components for improved file browsing experience, including sidebar navigation and content display.
- Updated `SpacedriveColors` to reflect the use of native macOS colors for traffic lights, simplifying color management across the app.
