Overview

Runs one external command (Kamal, in practice) via Open3.capture3 and reduces it to the three things WideEvent::Setup::Checker actually needs: whether it succeeded, and its stdout/stderr text. argv is always an array of literal strings (the executable and its arguments, never a single shell string), so no argument is ever re-interpreted by a shell. This is the only piece of Checker that ever shells out; every test replaces it with a fake that returns canned Results instead.
