v0.3.1 — staged, verification pending

Publication status — verification pending

This GitHub release was staged before the publication hardening merged in
PR #728. Its retained archives
and evidence remain available for audit, but they do not include the final
verification marker required by the current publication contract and therefore
must not be treated as proof of a Supported envelope-matching release.

The documentation site intentionally keeps envelope matching at Beta until
the release assets pass the hardened verifier and a digest-bound verification
marker is uploaded last. rustqec-cli 0.3.1 has not been published to
crates.io. Follow the remaining publication work in
#720.
