Switch to a new way of building node code as single binary executable

[morningspace]

Currently we use pkg as the tool to build node code into single binary executable. This has been deprecated according to the pkg maintainer. See: https://github.com/vercel/pkg.

Important
pkg has been deprecated with 5.8.1 as the last release. There are a number of successful forked versions of pkg already with various feature additions. Further, we’re excited about Node.js 21’s support for single executable applications. Thank you for the support and contributions over the years. The repository will remain open and archived.

We need to find new way to replace pkg, e.g.: use the single executable applications feature provided natively by nodejs.
