nandesu/hermes3d ? reverse-engineered prompt

Build me a self hosted web app called Hermes3D that feels like a live 3D office for AI agents.

I want to open it in the browser, connect it to an agent backend, and then see agents moving around a retro office in real time. The app should let me chat with agents, create and manage them, edit their settings, watch sessions and approvals, and see activity updates as they happen. It should also have a place to build and publish office layouts, plus a demo mode so I can explore everything without a real backend.

Make it feel like an actual workspace, with standups, code review, monitoring, and a janitor or reset style control for cleaning up sessions and context. Save local preferences like the selected backend, focused agent, desk assignments, and office state. If you need current docs for the backend connection or runtime details, look them up online.
