Safety and Crisis Protocol

ca/safety/risk.py flags crisis/self-harm/violence/manipulation terms.
ca/safety/protocols.py overrides responses at MEDIUM/HIGH safety levels with grounding and emergency guidance.
Doctrine rules add blocks for exploitation, deepfakes, fraud, privacy violations, and governance duties.
All outputs funnel through structured replies to avoid ambiguous tone or unsafe improvisation.
Escalation guidance always recommends professional/local emergency help when imminent danger is detected.
