Two RED tests pinning that `aura run` refuses cleanly (exit 1 + an aura: message) rather than panicking on a user-authorable blueprint: a tap wire pointing out of range (run_signal_r's compile .expect swallows TapWireOutOfRange into a panic, main.rs:1753) and an exposed output not named bias (wrap_r's g.build().expect panics on UnknownOutPort from the hardcoded bias weld, main.rs:1667). Surfaced by the measurement-milestone fieldtest. refs #282
