Releases now carry one archive per architecture with a static awg-control
binary (services and CLI), the built frontend and .env; the installer no
longer installs Node.js or runs npm.
- tools/release/package.sh: CGO-free builds for linux/amd64 and arm64,
version injected into `awg-control version`; used by both the GitHub and
Gitea release workflows
- install.sh: architecture check, per-arch archive, /usr/local/bin/awg-ctrl
is a symlink to the binary, systemd unit without node in PATH, steps
renumbered 1/6..6/6
- update from a Node install: the old services are stopped through the old
CLI, then TS sources, node_modules and the old dist are removed; cli.env,
panel.id and logs stay
- README: one binary, its roles, architecture requirement
