Add PerspectiveGap community eval tasks

[WhymustIhaveaname]

Summary

Adds PerspectiveGap as two community reference tasks:

• role_assignment
• prompt_writing

The tasks load either a local JSONL file at data/perspective_gap/evaluations.jsonl or the Hugging Face sun1245/PerspectiveGap test split, call the configured sampler with the task prompt, and score with the official deterministic perspective_gap.scoring functions.

Notes

• Registers both tasks in evaluate.py.
• Pins the PerspectiveGap scorer dependency to commit 9c6921b3337ff3e6a6a453f68d117a8c1663135e.
• Fails fast when the scorer dependency is missing, before sampler calls start.
• Keeps sampler and runtime scorer errors as per-sample failures.
• Adds a root test_perspectivegap_smoke.py so default pytest discovery includes the smoke tests.
• Updates both README.md and README_zh.md.

Validation

uv run --no-project --python 3.13 --with pre-commit pre-commit run --files README.md README_zh.md evals/perspectivegap_eval.py evaluate.py requirements.txt test_perspectivegap_smoke.py
PYTHONPATH=. uv run --no-project --python 3.13 --with pytest pytest -p no:cacheprovider
git diff --check

Result: 7 smoke tests passed. Pre-commit and whitespace checks passed.

Caveat

This is a community reference contribution. The maintainer noted that this repository is not actively maintained, so review may be slow.
