SimWorld-AI/SimWorld-Studio — reverse-engineered prompt

Build me a usable local version of SimWorld Studio that I can open in my browser and use to chat my way into creating and testing 3D scenes. I want the main experience to feel simple, pick a coding agent like Claude Code or Codex, type something like “make a sunny neighborhood with four houses and trees,” and see the scene appear in Unreal with a live streamed viewport when Unreal is available.

Please wire up the normal startup flow so one command launches the web app and backend, connects to Unreal on Windows or Linux, and serves the UI on port 3002. I also want the embodied agent side working enough to spawn agents, control them, and view basic experiment or trajectory info if that is already supported here. If I run this on a Mac, make the web stack still work cleanly even without Unreal, with clear disabled states instead of errors.

Please keep the setup practical, fix anything broken, and leave me with a short README section on how to run it. Look up current docs online if you need to.
