bug: full auto mode cannot build Go code

Question

I'm on MacOS working in a Go repository. In `--full-auto` mode, when codex tries to run `go build`, it runs into this error:

```
 go: creating work dir: mkdir /var/folders/zv/b1sjg_v16tn6dpgblz8v4ls40000gn/T/go-build3375040063: operation not permitted
```

I'm assuming it's a sandboxing problem.
