Describe the bug

Recent nightly from 2 days ago giving errors both on local and on CI

You can check a run https://github.com/superform-xyz/SuperVaults/actions/runs/11918496623/job/33216055316

If you run this repo on foundryup -C 9d74675 the error won't exist

Note: this is urgent as it is breaking all of our CI runs

Source of the error in solc: https://github.com/ethereum/solidity/blob/b0d991bd4b3bc2d48d40029c3303f67f604d7cc5/libsolidity/interface/FileReader.cpp#L128-L135

Possibly related to recent changes in https://github.com/foundry-rs/compilers? cc @klkvr / @DaniPopes / @grandizzy

yeah, was able to confirm was working before compilers update in #8668
Workaround until a fix would be to change root prj remapping to 'forge-std/=lib/superform-core/lib/forge-std/src/', https://github.com/superform-xyz/SuperVaults/blob/main/foundry.toml#L20

[grandizzy]

pretty sure the right fix would be the one for #9146 which should just ignore remappings from deps if already present in project root remapping

I believe this is the source of the CI errors we're seeing on FlexVoting as well. CI was passing until nightly-e649e62, failing after. Pinning to e649e62 fixes it.

I am not sure is the same issue, I am not able to replicate the failure locally with master, did you try with latest nightly and still fails? thank you
