.github/dependabot.yml (1)

8-10: LGTM - sensible ignore rule for controlled Node version management.

Ignoring major @types/node updates prevents unwanted PRs for type definitions that don't match your supported Node versions. Just remember to manually update @types/node when you bump the minimum Node version in the future.

package.json (1)

42-44: LGTM - engine requirement correctly updated.

The engines.node field is properly updated to >=22.0.0, and @types/node at ^22.10.5 (line 59) is consistent with this requirement.

.github/workflows/ci.yml (1)

13-15: No action needed. Node.js 24 was already released on May 6, 2025, and entered Active LTS on October 28, 2025. The matrix configuration is appropriate and Node 24 is fully available in actions/setup-node.
