Pre-PR security review of your current branch or git diff. Use when the user says "review my changes", "ready to merge", "pre-PR check", "security review before PR", "endor review", or is about to create a pull request. Runs dependency checks, SAST, secrets detection, and license compliance as a security gate. Do NOT use for scanning repos outside the current branch (/endor-scan) or checking individual packages (/endor-check).
