Invalid cross-device link

[jonathanpwang]

Recently, this workflow is giving errors when used on AWS self-hosted GPU runners:

Example: https://github.com/openvm-org/stark-backend/actions/runs/17200888597/job/48791119926?pr=102

Error snippet:

error: could not rename component file from '/home/runner/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/share/doc/clippy' to '/home/runner/.rustup/tmp/qzwl4905618fqaq1_dir/bk': Invalid cross-device link (os error 18)

Internet/LLM searches say GPU instances are virtualized differently, but the same workflows used to run fine until 2 days ago, so I wonder if something has changed in the workflow to cause this?

I now add

      - run: |
          rustup component remove clippy || true
          rm -rf ~/.rustup/toolchains/stable-x86_64-unknown-linux-gnu || true

prior to

      - uses: dtolnay/rust-toolchain@stable

in all workflows to fix this.

To clarify, the workflow continues to work on all CPU runners, and the only change necessary to get to fail is to switch to a GPU runner.
