COMMIT_LIST only rendered the bare subject line per commit, with no
way to jump to that specific commit — only the triggering commit
(Source:) had a link. Each line now reads
"- [<short-sha>](<repo>/commit/<sha>) <subject>", matching the same
link style already used for Source.
The publish/release step had drifted from the sibling repos' reference
template: PR-number extraction relied on the local commit log after
the version-bump commit was already made, so it could never find the
triggering PR (that commit's own message has no PR reference) — fixed
by keying off github.sha, the fixed triggering commit, instead.
Also aligned: docker login casing (Djeex, not djeex), Trivy pinned to
0.74.0, deprecation check made informative instead of build-blocking,
publish skipped entirely when no container-relevant file changed, and
the release body now lists the individual commits (with a --- divider
under each heading) instead of the raw changed-files list.
