name: Release

# Tag a version (e.g. `git tag v0.1.0 && git push --tags`) to build the static
# binaries for every supported target and attach them to a GitHub Release. Those
# assets are what the npm wrapper's postinstall downloads and what a plugin can
# bundle — so this workflow is the single source of prebuilt binaries.
