feat: Python Self-Healing Supply Chain Demo (Interactive + Gemini 3)
📝 Summary
This PR adds a comprehensive Python sample demonstrating an Autonomous Supply Chain Agent capable of "Self-Healing" when a primary supplier fails. It leverages the Google Agent Development Kit (ADK) and the latest Gemini 3 Flash model to orchestrate a recovery workflow using UCP (Commerce) and AP2 (Governance) protocols.
