name: wai-quantum command line release

# On a tag wai-quantum-cli-v<version> (the version wai/wai-quantum-cli/Cargo.toml
# states), builds the wai-quantum binary on each runner and attaches it to the forge
# release of that tag, each archive with its SHA-256:
#   macOS      aarch64-apple-darwin and x86_64-apple-darwin, with the GPU state vector;
#   Linux      x86_64- and aarch64-unknown-linux-musl, static, so any distribution runs it;
#   Windows    x86_64-pc-windows-msvc, as a zip.
# Each binary is run once before it is packaged (`--version`, and `key --demo-key` for
# a did:key). A last job writes the Homebrew formula and the Scoop manifest for the
# archives just uploaded and attaches them too.
#
# Uploads go to the forge directly over the private network (FORGE_API), never through
# the public tunnel. A runner that is down leaves its platform's archive missing: the
# release lists what each build attached.
