🔧 Ignore @types/node in maintain:outdated

DefinitelyTyped keeps the @types/node latest dist-tag on the LTS line,
so check-outdated compared the current-line types against a lower
version: a permanent "reverted" flag, scan exit 1, zero signal. Ignored
by package name; --types filtering and a version-scoped pin rejected
(rationale in development/tooling.md).
