Improvements
- Removed the extension store experience from the app, including extension browsing, install/uninstall actions, download progress, and migration-related UI
- Clarified the product model so built-in modes ship directly with CodeSplash AI instead of being presented as separately downloaded extensions
- Simplified the desktop experience around one bundled application with a unified multi-mode workspace
- Aligned release and packaging behavior with the bundled-app model by removing separate extension package distribution behind the scenes
