+Pre-compute BERTScore reference responses for all 50 test prompts.
+For each prompt, finds the most semantically similar response in the
+Empathetic Dialogues test split using cosine similarity.
+Saves result to eval/bertscore_references.json.
+
+Run once from repo root:

+Takes ~2 minutes on CPU. Does not require GPU.
