Soup — one-command LLM fine-tuning

Soup turns fine-tuning into soup init → soup train with a single YAML config: task selection, quantization, batch size, and GPU/backend detection are all handled for you. Its headline feature, layer streaming (stream_layers: true), keeps the frozen base model out of VRAM and streams it one decoder layer at a time, so an 8B model can fine-tune on a 4 GB laptop GPU — measured bit-exact against a normal resident run.
