fix: mac-oui-lookup ESM/CJS interop crash on startup

Named import of a CommonJS module's export crashed the whole process
at boot (SyntaxError, not caught by tsc since it's a runtime module
resolution behavior, not a type error). Verified by actually running
the built output with node this time instead of trusting tsc alone.
