Function resolve_project 

pub fn resolve_project(
    layout: &Layout,
    explicit: Option<&str>,
) -> Result<String>

Resolve the project to act on. An explicit name wins; otherwise walk up from the current directory for .project-ctx.toml and read [project].name. Neither available is an error, so nothing is ever guessed silently.

Errors

Returns an error if the explicit project name is empty, no name can be resolved, the current directory cannot be read, or the name matches more than one project directory.
