✅ What's Good:

• Changes are confined to workflow files only
• Commit hashes are properly pinned for security

⚠️ Concerns:

This is a MAJOR version update which may include breaking changes. Before merging:

3. Check compatibility: Ensure v6 works with the Python 3.11-3.13 matrix

Recommendation:

Monitor the CI run for this PR. If all checks pass and there are no breaking changes in the v6 release notes, this should be safe to merge.

Status: Requires manual review - not auto-approved due to major version bump.
