Archiving Changes

Use when a change is complete and ready to archive.

Behavior

1. If change slug is not provided, ask which change to archive.
2. Default to syncing specs first using syncing-to-specs unless the user explicitly says skip.
3. Move docs/changes/<slug>/ to docs/changes/archive/<date>-<slug>/.
4. Remind the user to validate formatting after archive.

Notes

• Be transparent when syncing before archive.
• If the change is docs-only and should not update current specs, skip sync.
