Add support for image recognition

**Is your feature request related to a problem? Please describe.**

**Describe the solution you'd like**

I would like to be able to solve image challenge using AI object recognition

**Describe alternatives you've considered**

**Additional context**

No files, tests, or entry points are identified in the issue. First clarify whether image challenges are within scope despite the project note limiting support to reCAPTCHA audio challenges, then define the recognition approach and acceptance criteria; done would mean manually started image-challenge solving that meets those criteria.
