v1.1.0

• Ship an AI agent skill (resources/skills/rasuvaeff-bulkhead/SKILL.md +
  extra.skills in composer.json): projects using the llm/skills Composer
  plugin get the skill synced into .agents/skills/ automatically on install.
• Bump rasuvaeff/property-testing dev dependency to ^2.6.
• Property-generator methods in tests are now public static (private ones are
  removed by rector's RemoveUnusedPrivateMethodRector — they are only called
  via reflection).
