Added: support for gpt-4o-mini model in config.ts

- **WHAT**: Introduced `gpt-4o-mini` to the list of supported models in the `configValidators` and updated the default model in `getConfig`.
- **WHY**: To expand the range of supported models and provide a more lightweight option for users.
- **HOW**:
  - Added `gpt-4o-mini` to the array of valid models in the `configValidators` (line 104).
  - Updated the error message to include `gpt-4o-mini` (line 113).
  - Changed the default model from `gpt-4o` to `gpt-4o-mini` in the `getConfig` function (line 181).

These changes ensure that the new model is recognized and can be used as a default, enhancing the flexibility and options available to users.
