fix: engine requirement

[Rotzbua]

Summary

engines requirements causes problems.

Background & Context

The package is used to distribute finished builds that do not have any direct requirements for the node version used.

However, a modern nodejs environment is required for the build process. A different configuration is provided for this purpose: https://docs.npmjs.com/cli/v11/configuring-npm/package-json#devengines

Tasks

• CI should go green
• thows warnings on outdated node versions if try to build
• no warning on other installs

Dependencies

Pull request overview

This PR adjusts Node.js version requirements so consumers installing the published package aren’t blocked by a Node engine constraint, while still declaring a modern Node requirement for development/build workflows (per the devEngines approach referenced in the PR description).

Changes:

• Replaced engines.node >=20 with a devEngines configuration intended to warn (not fail) when the dev/runtime Node version is outdated.
• Removed the root package engines entry from package-lock.json to match the updated package.json.
