Initial Mastra AI Agent Design and State Management

Begin by designing the core agents for your warehouse system using Mastra AI. Define at least three agents (e.g., 'Observation Agent', 'Inventory Agent', 'Logistics Agent') with distinct roles. For each agent, describe its responsibilities and how it will utilize Mastra AI's built-in memory to maintain state regarding the warehouse layout, inventory levels, or drone positions. Outline a basic message passing structure between these agents.
