Display and filter security findings from Endor Labs. Use when the user says "show findings", "list vulnerabilities", "what did the scan find", "endor findings", "show me critical reachable vulns", or wants to browse/filter results after a scan. Supports filtering by severity, reachability, category (vuln/sast/secrets/license). Do NOT use for running a new scan (/endor-scan) or explaining a specific CVE (/endor-explain).
