Ollama v0.32.6: Qwen3.5 MLX Speculative Decoding, OpenAI-Compatible Streaming

Qwen3.5 is faster on Apple GPUs: the MLX engine now uses the model's MTP head for speculative decoding automatically.

/v1/chat/completions streaming now matches OpenAI's wire format: role only on the first chunk, finish_reason on its own chunk, and usage in a separate chunk with stream_options.include_usage.

Experimental image generation has been temporarily removed.
