Entry point / dispatcher for the security-harness. Use when the user asks for any application-security work - 'security review', 'audit this codebase', 'pentest', 'find vulnerabilities', 'check for SQLi/XSS/IDOR/SSRF', 'generate a security report/SARIF'. Interprets the request and routes it to the full sh-security-review pipeline, a single stage, or a single vulnerability-class knowledge base.
