setup.cfg: File does not exist during Docker build

`setup.cfg` does not exist but is being referenced during the Docker build process. Please remove any reference to this file if it no longer exists.

**Steps to reproduce:**

```bash
git clone https://github.com/openagents-org/openagents.git
cd openagents
docker compose up -d --build
```

The build will fail with `setup.cfg: file does not exist`.
