- Added `isElectronMode` function to determine if the app is running in Electron or a browser.
- Updated `SidebarHeader`, `TabBar`, and `TabbedLayout` components to conditionally render UI elements based on the Electron mode.
- Adjusted styles and settings gear icon visibility to enhance user experience in browser mode.
This commit improves the application's adaptability by ensuring that Electron-specific features are only available when appropriate.
