📄 Description

Add a modality-agnostic multimodal framework to the MLX runner:

  • MultimodalModel interface: extends Model with EncodeMultimodal() for preprocessing raw bytes (images, audio) and Prefill() for multimodal embedding construction and chunked forward passes.
  • Pipeline support: parse [img-N] placeholder tags in prompts, route multimodal inputs through model-specific encoding, and handle multimodal prefill with KV cache awareness.
  • Client plumbing: forward image/audio data from completion requests through to the runner pipeline.
