The changes in `ConfigStore.ts` include adding a new method `checkAndSetCompletionDefaults` to handle code completion model updates. This method ensures that if there are code models available and the complete model is not set or is not in the available code models, it will be updated to the first code model in the list. This commit message follows the established convention of starting with a verb in the imperative form and providing a clear and concise description of the changes.
