✨ feat(skills): curate code workflow skills

Add a Gitea CI triage skill with legacy web-log fallback, document first-party and third-party skill roles, and register selected third-party code workflow sources.

Remove the first-party bulk refactor workflow in favor of the registered codebase migration replacement.
