Summary of Changes

Hello @bl-ue, 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 implements a follow-up change to improve the robustness and maintainability of the CLI's session management. It standardizes the handling of the --resume flag's default behavior by introducing a constant and significantly expands test coverage for session listing and deletion, ensuring these features work as expected under various conditions.

Highlights

• Refactored --resume flag handling: The --resume command-line flag now uses a dedicated RESUME_LATEST constant instead of a hardcoded string 'latest' when no value is provided, improving code clarity and maintainability.
• Enhanced Session Management Tests: Comprehensive unit tests have been added for the listSessions and deleteSession functionalities, covering scenarios like listing sessions, deleting by UUID or index, handling invalid identifiers, and preventing deletion of the current active session.
• Type Safety Improvement: The CliArgs interface has been updated to reflect the use of typeof RESUME_LATEST for the resume property, enhancing type safety.

Code Review

This pull request follows up on #10719 by refactoring the magic string 'latest' for resuming sessions into a RESUME_LATEST constant and adding comprehensive tests for session listing and deletion functionalities. The changes are well-implemented. I've found one issue in the new test file sessions.test.ts where mock objects for SessionInfo include an extraneous displayName property that will cause a type error. I've left a comment with a suggestion to fix it. Otherwise, the changes look good.

The changes are applied consistently across the codebase. Additionally, a comprehensive new test file for session management (sessions.test.ts) has been added, which significantly improves test coverage for this functionality. The new tests are well-structured and cover a good range of scenarios. Overall, this is a high-quality contribution that improves the codebase.
