- [nitpick] The variable name #modelSearchQuery could be more specific. Consider #searchableModelQuery or #modelSelectorSearchQuery to better indicate it's specifically for the searchable model dropdown.

The error handling in #checkForUpdates should provide more specific user-facing error messages. Currently it only logs errors but doesn't inform users about update check failures.

The buffer overflow handling using splice(0, discarded) is inefficient for large arrays. Consider using a circular buffer or deque data structure to avoid O(n) array operations on every overflow.

The GitHub API fetch lacks timeout and retry logic, which could cause the update check to hang indefinitely. Consider adding a timeout and implementing exponential backoff for failed requests.

Multiple @ts-ignore comments indicate type safety issues. Consider creating proper type definitions for the DevTools context or using type assertions with proper typing instead of suppressing all type checking.
