"""
ADK Orchestrator — Native Google ADK Integration
================================================
Wraps the Genesis Superior Browser (GSB) stack directly into 
Google Agent Development Kit (ADK) native tools. This allows 
Gemini 3.0 Flash to control the full L5 Supremacy stack 
(Stealth -> Vision -> Lux -> Delegation) natively.
