      Honcho provides a sophisticated memory and reasoning system for AI agents:
      - Rich Reasoning System: Multiple implementation methods that extract
        conclusions from interactions and build comprehensive peer representations
      - Chat API: Reasoning-informed responses integrating conclusions with context
      - Background Processing: Asynchronous pipeline for expensive operations
      - Multi-Provider Support: Configurable LLM providers (OpenAI, Anthropic, Google, Groq)
      - REST API server for easy integration with any application
      - PostgreSQL with pgvector for storage
