This currently always save a checkpoint per generation - we could also add a setting to control this

i feel like a better mechanism would be to have a var that is the target directory, which we'd both dump to and resume from.
it seems important that this is opt in like triton crash dump & like aot tuning directories, otherwise i'd worry we just accumulate trash somewhere.
