@r-near to fix the CI I think we need to use the cargo_near_build here

near-plugins/near-plugins-derive/tests/common/repo.rs

Line 38 in 7b47dbe

let toolchain = read_toolchain(project_path).await?;

like we did it here https://github.com/Near-One/omni-bridge/blob/f1ad7015414e6cff49d7ba793c13742eb02ff380/near/omni-tests/src/helpers.rs#L20

The current issue with this PR run is that near-sandbox is not able to deserialize the contract: CompilationError(PrepareError(Deserialization)) - this is because the near sandbox version is too outdated.

Looking at the code, it seems the existing code does indeed reference the correct Rust toolchain (1.83.0 in this case) to build the .wasm binary - the problem is the sandbox binary is too old to support 1.83.0-built contracts (I think).

There's some discussion here about how this error comes up:

• Contract fails with error {"CompilationError":{"PrepareError":"Deserialization"}}} near/near-workspaces-js#225

The reason it works on my local machine is because my personal toolchain is 1.83.0 (so it can bypass the home dependency issue, since it's a dev dependency) - but the contracts are built with 1.80.0. I suppose we could do something similar here by simply writing channel = 1.83.0 into the root rust-toolchain file. I tested it and it works locally - however there's a section in the README explicitly saying we shouldn't do that 🤷‍♂️
