Frox AI — Image Analysis Tool

Deliberately thin: this just calls MorphInferenceEngine.understand_image(),
which runs Morph's own vision encoder + LLM (see
multimodal/vision/encoder.py and inference/engine/morph_engine.py).
No external vision API — "image analysis" here means Morph looking at
the image itself, not a wrapper around someone else's vision model.
