[Feature Request] Architecture and UX Improvement

[dataCenter430]

Questions

Hi, @Wendong-Fan Eigent-ai team.
I took a deep look and found some potential issues for architecture, UX, backend and infrastructure on Eigent.

1. Electron single-instance lock in dev

• requestSingleInstanceLock() can cause dev server to exit when a second instance starts.

2. Layout visibility race

• setWaitingBackend() can briefly show the install screen after content has already rendered.

3. Zustand hydration

• Persisted auth may hydrate after the first render, causing temporary redirects or flicker.

4. Norate limiting

• Endpoints are not rate-limited, increasing abuse and Dos risk.

5. CORS configuration

• Missing or overly permissive CORS can allow unwanted origins

6. Backend API keys in env

• API keys and config are set in os.environ per request.

I'm confident that they will be addressed by me.
Please assign it to me, so I can implement the improvements soon.
Thanks
