chore: allow 'design' commit scope

[Israeltheminer]

Summary

Adds design to the commitlint scope-enum so design-focused commits (e.g. b042771 feat(design): account, 2FA, governance, and logs pages) no longer need to reach for a generic scope.

Split out of #1603 per CodeRabbit feedback — that PR's commits don't use the new scope, so it didn't belong there.

Test plan

• echo "feat(design): test" | bunx commitlint exits 0 on this branch

Summary by CodeRabbit

• Chores
  • Updated development configuration to support additional commit message scope conventions.
