Nefesh Human State Agent

Provides real-time human physiological state awareness for AI agents. Fuses biometric signals (heart rate, HRV, voice, facial expression, text sentiment) into a unified stress score (0-100) with behavioral adaptation prompts. Includes trigger memory for cross-session psychological context and adaptation effectiveness feedback.
