### Bug description

I'm building an extension for formatting my thesis at Oxford. Let's say I have the following bare-bones extension:

```yaml
title: Oxford Thesis Format
author: Benjamin Lee
version: 0.1.0
contributes:
  format:
    pdf:
      format-resources:
        - ociamthesis.cls
```

When I render the PDF on my Mac, it works _but_ the .cls file isn't cleaned up as would be expected.
