Overview

Opal's Module#prepend raises "Prepending a module multiple times is not supported" when a module is already in the target's ancestor chain. MRI's prepend is idempotent in that case (no-op, no error).

Our top-level lib files (lib/lutaml/model.rb, lib/lutaml/xml.rb) can be re-evaluated under Opal's eager loader, which would trigger the raise on the second pass. Align Opal with MRI by making prepend a no-op when the module is already present.
