PR Summary

Low Risk
Changes are limited to MDX migration blog content with no runtime, auth, or build-logic impact.

Overview
The v16→v18 migration post now documents the @nodejs/dns-lookup-options-coercion codemod for DEP0153 (typed dns.lookup / dns.promises.lookup options), with registry link, npx command, and before/after examples for callback and promises APIs. The err-invalid-callback section heading is pluralized to Examples to match the added pattern.

The v22→v24 guide adds a one-shot npx codemod run @nodejs/v22-to-v24 command and an info AlertBox clarifying that the listed codemods are not exhaustive.

• The phrase “run all of them at once” is ambiguous here given the note that the list of codemods for this migration is not complete. Clarify that the command runs the codemods listed in this guide (or the preset), not necessarily every possible codemod for the migration.

If you want to run all of them at once, you can use the following command:

• The doc suggests running all v22→v24 codemods via npx codemod run @nodejs/v22-to-v24, but that preset/package does not appear to exist in the Codemod Registry (the registry URL for it returns 404). This would cause the command to fail for readers. Consider replacing it with a single shell command that chains the individual codemods listed below in this guide (or link to an actual preset if one exists).

If you want to run all of them at once, you can use the following command:

```bash
npx codemod run @nodejs/v22-to-v24
