Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces the ability for users to display their machine's hostname within the CLI footer interface. By integrating the system's hostname into the existing footer selection menu, users gain better visibility into their current environment directly from the command line.

Highlights

• Hostname Integration: Added the machine hostname as a new selectable item in the CLI footer configuration.
• UI Component Update: Updated the Footer component to retrieve and display the system hostname using the Node.js os module.
• Test Coverage: Updated the footer items test suite to include the new hostname configuration.

Code Review

This pull request adds a 'hostname' item to the CLI footer, updating the configuration, tests, and the Footer component. The review feedback suggests optimizing performance by moving the os.hostname() call to a module-level constant to avoid redundant system calls during component re-renders.
