Add a comprehensive child safety standards page at /safety/child-safety that outlines Coves' policies and practices for preventing, detecting, and responding to child sexual abuse and exploitation (CSAE/CSAM). Changes: - Add GET /safety/child-safety route in web routes - Add ChildSafetyHandler to render the safety page - Create child-safety.html template with full policy documentation The page covers prohibited content definitions, age requirements (18+), reporting mechanisms, response procedures, AT Protocol federation handling, and compliance with NCMEC reporting requirements.
