S0-QA-01: Golden PRs & Evaluation Rubric

[ezeanyicollins]

Scope: Provide golden PRs and rubric to evaluate PatchPro’s suggestions.

Tasks:

• Create 3–5 golden PRs with common issues (unused import, missing docstring, etc.).
• Document expected PatchPro comment for each PR.
• Define rubric: detection, correct diff, clarity.
• Track pass/fail results per golden PR.

DoD: For each golden PR, PatchPro’s sticky comment can be compared against the expected one, and rubric can score pass/fail.
