model-mapper 1.3

Added

• vision_mappings per upstream for routing image requests to image-capable models.
• Xiaomi MiMo vision model support via mimo-v2-omni on the Anthropic-compatible endpoint.
• Web UI fields for configuring text and image models separately per tier.
• Regression tests for image request detection, vision routing, and missing vision-model errors.

Changed

• Requests containing Anthropic image blocks now use vision_mappings instead of text mappings.
• Sample config and README now document text versus image model mappings.

Fixed

• Image requests no longer get sent to text-only upstream models such as mimo-v2.5-pro.
• Upstreams without vision mappings now return a clear configuration error for image requests instead of forwarding to an unsupported model.
