 * ARCHITECT Agent Service
 * Creates a class of meta-agents whose sole purpose is to:
 * 1. Read other agents' configurations and track records
 * 2. Analyze performance and identify improvement opportunities
 * 3. Propose optimized versions (v+1) of existing agents
 * 4. Deploy improved agents via the ReproductionService
 *
 * From Eigenform Ontology: "An agent that only cooperates stagnates.
 * An agent that only competes fragments. Mastery is the balance."
