name: Release

# Build the agent for every supported target on a version tag and attach the
# archives to a GitHub release. Linux is a fully static musl binary (built with
# cargo-zigbuild) so one artifact runs on any distro — Arch, Alpine, NixOS, old
# glibc systems alike — and can then be repackaged however a distro prefers.
