- Add version: 1.0.0 to all 25 skill YAML frontmatters
- Create VERSIONS.md manifest listing all skill versions
- Add update check instructions to AGENTS.md
This enables users to be notified of skill updates and easily
pull the latest changes when 2+ skills are updated or there is
a major version bump.
