Enhance build process and server version management

Refactor build-linux-bundle.mjs to include package version and build number from environment variables and package.json. Update headless.js to streamline initialization and improve error handling. Introduce serverVersion.js to centralize version information retrieval, replacing redundant code in localserver.js. Enhance logging in index.js to display build number and version more clearly.
