test(plugin): compare plugin-provided command execution against upstream

A Shirabe-authored CommandProvider fixture plugin (greet) runs under both
implementations: exit codes, the command's own output, help/list rendering,
alias resolution, a validation failure, and a file recording the shared
object graph the command observed (root package, strict application FQCN,
and the exit code of the built-in about command it invoked) must match.
