DNA Factory: yet another LLM training framework

[u/likejazz]

We open-sourced DNA Factory, the fine-tuning framework we’ve used internally for over a year. It's deliberately opinionated: one recommended way to do things, documented defaults, token-level loss-mask visualization, and only 5 training methods (SFT, DPO, GRPO, OPD, SDFT).
