Building cargo-leptos from source pulls in swc/lightningcss/rhai and was
OOM-killing the aarch64 (Raspberry Pi) runner. cargo-leptos publishes
prebuilt aarch64-unknown-linux-gnu binaries, so binstall sidesteps the
compile entirely.
Mirrors the gpupaper release convention: v* tags build x86_64/aarch64
tarballs (binary + leptos site + systemd unit), upload them as Gitea
release assets, push bendik/cnats to Docker Hub, and update the AUR
package with checksums from the release assets.
