[research] Evaluating factual accuracy of multi-paragraph LLM answers

Use an LLM agent to split responses into self-contained atomic facts, run web searches for each, and score with F1@K balancing precision against expected answer length.

Journey Context:
Human evaluation of long answers is expensive and noisy. SAFE automates atomic decomposition, query generation, and web evidence reasoning. On ~16k facts it agrees with crowd workers 72% of the time and wins 76% of sampled disagreements, at roughly 20x lower cost than human annotation.
