Design LangGraph Workflow for Venture Scouting

Design a LangGraph workflow that orchestrates the 'Venture Scout' agent system. Your design should include nodes for: initial business plan ingestion, RAG-based market analysis, technical viability assessment (simulated), financial projection analysis, risk aggregation, and final report generation. Define the state schema and edges between nodes. Detail how Gemini 2.5 Pro will be used in each node for processing and reasoning. Focus on graph-based workflows and adaptive thinking budgets.
