OllamaUnloadModel now works as a pass-through node: wire OllamaChatCompletion.response into the optional `passthrough` input and OllamaChatCompletion.model_name into `model` — ComfyUI's data-flow graph then guarantees Load → Chat → Unload execution order. OllamaChatCompletion gains an optional `model_name` forceInput so OllamaLoadModel.model_name can wire in (creating Load → Chat ordering) and overrides the COMBO dropdown. It also returns `model_name` as a 3rd output so the model can flow downstream to UnloadModel without duplication.
