Summary

This PR updates the actions/checkout GitHub Action from v4/v5 to v6 in two workflow files.

Critical Issues

None found ✅

This is a straightforward dependency update of a GitHub Action. The changes:

• Update .github/workflows/claude-code-review.yml from v5 → v6
• Update .github/workflows/claude.yml from v4 → v6

These workflow files are infrastructure changes, not TUnit code, so the critical TUnit rules (dual-mode, snapshot testing, VSTest prohibition, performance, AOT compatibility) do not apply.

The v6 update includes:

• Credential persistence improvements
• Node.js 24 support

Both workflow files maintain the same configuration (fetch-depth: 1), so there are no behavior changes beyond the action version upgrade.

Verdict

✅ APPROVE - No critical issues

Summary

This PR updates the actions/checkout GitHub Action from v4/v5 to v6 in two workflow files.

Critical Issues

None found ✅

This is a dependency update managed by Renovate Bot that:

• Updates GitHub Actions workflow files (infrastructure/CI, not production code)
• Does not touch any TUnit source generator, engine, or test code
• Does not modify public APIs, reflection code, or hot paths
• Does not violate any TUnit critical rules

The changes are minimal and low-risk:

1. .github/workflows/claude-code-review.yml: v5 → v6
2. .github/workflows/claude.yml: v4 → v6

According to the release notes, v6 includes:

• Credential persistence improvements
• Node.js 24 support

These are infrastructure improvements with no impact on TUnit's functionality.

Suggestions
