Fixed in commit 23dd071. I analyzed the failed checks and resolved the npm peer dependency conflict by reverting @eslint/js to ^9.39.4 (compatible with the current ESLint/plugin set), then re-ran npm ci (npm 10), npm run lint, npm test, and npm run build successfully.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
