Subject: [PATCH] ci: add release workflow that builds binaries and publishes
 SHA256SUMS

Pushing a tag matching v* (or running the workflow manually with an
existing tag) cross-compiles the four supported targets via
`make build-all`, generates a SHA256SUMS file, and publishes a GitHub
release with all binaries attached.
