Release Reviewer Checklist

Check before merging. PR Hygiene CI is intentionally skipped on release-please PRs — these boxes are for the human merging the release.

• Version bump matches expected scope (no surprise major from a stray feat!:)
• CHANGELOG entries read correctly and credit external contributors
• No security-sensitive deps changed without prior review
• Downstream consumers (build123d, ocp_vscode, mat-vis-client) still compatible
• Migration notes (if breaking change) present and linked from CHANGELOG
• All required CI checks green
