Disentangle scaffold and dataset

[mikasenghaas]

@daniel can add some color here as well, but the gist of it is not clear how to handle scaffolds/ datasets, e.g. for SWE environments we have

• scaffolds: mini swe agent plus, deepswe
• datasets: deepswe, swe bench verified, swe smith/ etc.

should there be one env per scaffold with configurable dataset? one env per dataset with configurable scaffold? one env per scaffold and dataset?

for reference take a look at deepswe or mini_swe_agent_plus environments.
or as discussed here
