Purpose
Backport of #177 to
release-0.3.Make source release archives reproducible across macOS and Linux and ensure that the artifact tested by GitHub Actions is the exact artifact signed and staged by the release manager.
The packaging flow previously allowed platform gzip implementations to produce different compressed bytes. This backport requires GNU gzip with fixed options, makes the workflow artifact canonical, downloads and signs those exact bytes, and verifies byte-for-byte reproducibility from the signed RC tag.
The verifier also reuses an isolated KEYS keyring for both artifact and tag signatures, including unsigned CI artifacts. Focused tests cover gzip selection, inherited gzip options, signed-tag verification, and inherited Git signing configuration.
