.install_default_skills(opts = {}) ⇒ Object

Seed bundled skills into ~/.pwn/skills (or pwn_skills_path:). Every SKILL.md under etc/default_skills is copied, preserving relative path. SOP SKILL.md files are left alone so operator edits survive upgrades. Generated module skills under pwn/ are overwritten by ModuleSkills.install. scripts/ are never copied from the gem templates.

Extracts an Array of reference strings (URLs, CWE/CVE/ATT&CK ids, etc.) from a skill body. Supports three sources, merged & uniq'd:

1) frontmatter `references:` (legacy pwn)
2) frontmatter `metadata: { references: [...] }` (spec-conformant slot)
3) markdown `## References` bullet section
