🔧 Ignore @types/node in maintain:outdated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so check-outdated compared the current-line types against a lower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).

+### `maintain:outdated` ignores `@types/node`
+
+#### Decision (2026-09)
+
+Pass `--ignore-packages @types/node`.
+
+#### Why
+
+- DT pins `@types/node`'s `latest` dist-tag to LTS (22.x); current-line types
+  ride other tags. Scan sees latest < installed — permanent "reverted", exit
+  1, zero signal. `--ignore-pre-releases` no help: 22.20.3 is stable.
+
+#### Rejected
+
+- `--types major,minor,patch`: hides real reverted reports elsewhere.
+- `@types/node@26.*`: tag stays wrong across majors; un-pin per bump = ritual.
+
+#### Known issue
+
+- A genuinely behind `@types/node` goes unreported; match it to
+  `.node-version` by hand.
