Go service (nasmon/) plus nfpm packaging (packaging/), carried over from the home_nas monorepo. Adds rpm packaging alongside the existing deb build (Fedora/RHEL/Rocky dependency names via nfpm overrides, per-format systemd unit path, dpkg+rpm-compatible maintainer scripts) and a Gitea Actions workflow that builds both formats on every push.
