Guards call to the user-defined entrypoint by #[cfg(target_os = "zkvm")].

This is helpful to prevent errors when compiling against a non-zkVM target, which can often happen when a program is included in the root workspace and users clone and simply build everything in the workspace.

Ideally, users should exclude zkVM programs when building against the host target, as it's wasted work anyway. However, wasted work is still better than throwing a compilation error directly.

Why do we need all of these to be pub?

Because otherwise they would be marked as unused when building against the host, so you get false positives running say cargo clippy. The template repo has it as pub too.
