Pull request overview

This PR adds a new GitHub Actions “skill” documenting safe git add --renormalize usage and updates workflows to avoid CI failures caused by pathspec patterns that match no files. It also regenerates the skills index to include the new skill and updated tag counts.

Changes:

• Added .llm/skills/github-actions/git-renormalize-patterns.md describing best practices for validating git add --renormalize patterns and keeping workflow patterns in sync.
• Updated .github/workflows/prettier-autofix.yml and .github/workflows/format-on-demand.yml to remove *.markdown/*.asmref from git add --renormalize and file-pattern sections, and to include YAML patterns where appropriate.
• Regenerated .llm/skills/index.md and cross-linked the new skill from workflow-consistency.md and the skills index/tag cloud.
