Module structure 

Directory structure validation for skill packages. Directory structure validation for skill packages.

Extends validation beyond frontmatter to check the skill’s directory structure: file references in the markdown body, script permissions, reference depth, and nesting depth.

Structure diagnostics use codes S001–S005. Most are Severity::Warning unless the issue would cause a broken skill at runtime. S005 (symlink detected) uses Severity::Info.
