AI-Generated Description

Summary

Automated bump of the SHA-pinned Uniswap/ai-toolkit reusable workflow references from 96ef665ba04221de07e94fcc3ea69fe32c7cf306 to c4820d6e62a9488c831e722aac202733fafab5dd.

Changes

• .github/workflows/claude-code-review.yml: bump uses: pin for _claude-code-review.yml
• .github/workflows/claude-pr-metadata-update.yml: bump uses: pin for _generate-pr-metadata.yml

Notes

• Pin-only change — no workflow triggers, inputs, or secrets were modified. The caller-side fork-author guards added in fix(ci): bump ai-toolkit reusable workflows past #453 RCE hardening #479 are unchanged.
• Both files lost their trailing newline in this update; harmless for YAML parsing but worth restoring on the next touch.
