Subject: [PATCH] ci(develop): build image in parallel with tests, gate only
 the publish
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two-phase scheme instead of the sequential gate: the build job runs in
parallel with test/e2e jobs and only warms the buildx GHA cache
(push:false, cache-to mode=max); a new publish job (needs: test,
e2e-server, e2e-mcp, build) rebuilds from the warm cache (near-instant
on hit, full rebuild on eviction — same as the old sequential timing)
and pushes :develop. GHCR login moved to publish; build-args blocks are
kept textually identical between the two jobs so the cache hits.
