Summary of Changes

Hello @adamfweidman, 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 addresses an issue where model availability status might become stale after an authentication change. By introducing a mechanism to reset the ModelAvailabilityService whenever the authentication method is refreshed, the system can now ensure that it always operates with current and accurate model health information, thereby improving reliability and preventing potential issues related to outdated service states.

Highlights

• Model Availability Service Reset: A new reset() method has been added to the ModelAvailabilityService to clear its internal health state, ensuring that model availability data can be refreshed.
• Authentication Refresh Integration: The refreshAuth method in the Config class now calls the modelAvailabilityService.reset() method at the beginning of its execution. This ensures that model availability status is cleared whenever the authentication method is changed or refreshed.
• New Test Coverage: A new test case has been added to config.test.ts to verify that the modelAvailabilityService.reset() method is correctly invoked when config.refreshAuth() is called.

Code Review

This pull request introduces a mechanism to reset the model availability service when the authentication method is changed. This correctly handles scenarios where model availability (e.g., due to quotas) might differ between authentication contexts. The implementation is clean and simple, adding a reset() method to ModelAvailabilityService and invoking it within refreshAuth. The change is well-supported by a new unit test that verifies the reset logic is triggered as expected. Overall, this is a good improvement for the application's robustness.
