Description

We have some tests defined using shell scripts, and most of these only run on CI. Change them to be run as part of cargo test.

To aid with this we could rejig the entrypoint code so we could run CLI commands from within the Rust code, passing the working directory as an argument.

let cd = Utf8PathBuf::from("tests/some_project")
let result = cli::main(cd, ["export", "escript"]);
snapshot!(result);

Research direction
Examine the current shell script tests in the repository, typically located under tests/ directory. Understand the CLI entrypoint structure in src/main.rs or similar. Then refactor the entrypoint to accept a working directory as argument, enabling direct Rust calls. Write Rust tests using snapshot testing.
