fix(tests): exclude YAML frontmatter source metadata from path rewrite check

The codex and kimi SKILL.md files have 'source: templates/commands/...'
in their YAML frontmatter — this is provenance metadata, not a runtime
path that needs rewriting. Strip frontmatter before checking for bare
scripts/ and templates/ paths.
