validateForeignRefs walks the merged tree (libraries + named c units, nested namespaces included) and diagnoses any #foreign whose ref names neither — a typo'd ref previously compiled and resolved silently through whatever image carried the symbol. Decls synthesized from #include headers carry no ref and are exempt. Flips the C0.2b pin; zero collateral across the 608 other examples.
