Contributions summary:Lucas primarily focused on adding and enabling end-to-end (E2E) tests for the Theia IDE's packaged application. They implemented tests using WebdriverIO to verify the application's functionality, including window titles and the presence of built-in extensions. Furthermore, the user ensured these tests were compatible across multiple operating systems by adapting the test setup and keyboard shortcut configurations for Windows and macOS. They also made other contributions like ESLint configuration.
