Synchronizes workflow templates from stranske/Workflows into this repository, updating the verification-to-new-PR workflow action pins and adjusting the metrics aggregation script’s parse-error detail handling.

Changes:

• Pin third-party GitHub Actions in agents-verify-to-new-pr.yml to full commit SHAs (with major-version comments).
• Improve aggregate_agent_metrics.py parse-error detail accumulation when the stored-detail limit is reached (dedupe/overflow behavior + guard for non-positive limits).
