Fixed

• inheritance-convention-violation no longer flags a class that extends another
  class of the SAME role as the archetype's dominant base (a *Controller
  extending a project Admin::SettingsController, a *Serializer extending
  another *Serializer). Such a superclass is a sibling or intermediate of the
  same role that itself roots at the archetype's base -- intra-role reuse, not a
  wrong-base deviation. Only a CROSS-role base (a controller extending a Model) is
  now flagged. This eliminated the last large residual false-positive class (30 of
  31 remaining inheritance firings on a real Rails repo were same-role
  extensions), while a genuine cross-role deviation still flags. The role word is
  the trailing CamelCase word of the base name (BaseController -> Controller),
  matched case-sensitively (so Microservice is not treated as a Service role),
  and generic trailing words (Base, Error, Class, ...) grant no exemption so
  a class extending an unrelated *Base still flags.
