"""Precision and recall per role of a role predictor against the labels.

    python3 scripts/evaluate_roles.py predictions.jsonl [--projects kiwi,mall-swarm]

predictions.jsonl holds one {"id": "<project>/<qualified name>", "role": "<role>"} per line;
a missing id counts as "none". "none" predicted is no prediction: a miss counts against
the labelled role, not as a false positive of "none". See results/agentkit-roles.predictions.jsonl.
