fix: double-escape newlines in Node version guard banner string

The \n in a TypeScript template literal becomes a literal newline in the
JS output. Inside a double-quoted JS string that is a SyntaxError. Use
\\n (four backslashes in TS source → \n in JS output) so the runtime
sees proper escape sequences and prints formatted output.
