Implementation LGTM, would you mind adding a test case for this?

lgtm! one minor question re testing the new setting

.with_max_persisted_states(Some(10_usize))
.with_blocktime(Some(Duration::from_millis(1))),
)

is there a way to assert file was actually written in custom temp dir? I tried to manually test it but probably I am missing something as I wasn't able to get the json file dumped

thank you! yeah, managed to check file is generated with this test. I think that's good to have, drawback is that will slow down the CI (and potential flakiness), @zerosnacks wdyt?

If we are to keep it let's solve warnings here
https://github.com/foundry-rs/foundry/actions/runs/11933626813/job/33261072474#step:12:66

and maybe add one more assert to make sure the cache is actually populated

assert!(cache_path.read_dir().unwrap().next().is_some());
