Subject: [PATCH] fix: copy frontend dist into backend-builder for go:embed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The backend Go build embeds the frontend via //go:embed frontend/dist
in internal/static/static.go. The Dockerfile was missing a
COPY --from=frontend-builder step to place the built dist at the
expected path before running go build, causing the build to fail.
