vbatts/slackware:15.0 ships neither git nor its runtime shared libs
(nghttp2, brotli, cyrus-sasl) or ca-certificates, so actions/checkout
was failing immediately with "base image is missing git/tar". Install
git and its dependencies from Slackware's own official mirror, pinned
by exact filename and verified SHA256, and build the CA bundle so git
can trust HTTPS remotes. Verified end-to-end against the real Gitea
instance (git ls-remote succeeds) in a fresh vbatts/slackware:15.0
container.
