- Refactored market_intel_orchestrator.py for direct Gemini API (v1) calls.\n- Updated model to gemini-2.5-pro for enhanced capabilities.\n- Implemented minimal stdout logging for improved traceability within Docker.\n- Optimized Dockerfile and introduced market-intel.requirements.txt for leaner, faster builds.\n- Ensured end-to-end communication from React frontend through Node.js bridge to Python backend is fully functional.
