/// Maps a returned [`anyhow::Error`] to the right exit code via
/// [`runner::exit_code_for_error`] — `ResolveError` → 2, everything else
/// → 1. The default `Termination` impl on `anyhow::Error` collapses
/// every failure to 1 with the same printed format, which is what was
/// happening before this binary started caring about resolver-specific
/// failures.
