Subject: [PATCH] fix: resolve langgraph version conflict and sync start.sh
 with README

- Upgrade langgraph>=1.1.0,<1.2.0 and langgraph-prebuilt>=1.0.11,<1.1.0
  to fix ImportError: cannot import name 'ExecutionInfo' from langgraph.runtime
- Add missing python-multipart dependency (required by FastAPI file upload)
- Fix start.sh conda env name: polystudio -> agentImage to match README.md
- Make start.sh executable (chmod +x)
