Function: createErrorKit()

Each call declares its own class (never shared), so two kits' instances never satisfy each other's instanceof; name becomes both the runtime .name and the stack-trace identity.

createErrorKit<R extends Registry, Name extends string>(name: Name, registry: R): ErrorKit<R>
