Goal

Split the Dockerfile into a dedicated lint stage using the pre-built golangci/golangci-lint image, so lint and formatting failures surface much faster without downloading golangci-lint on every build.

Key details

Lint stage: golangci/golangci-lint image runs make fmt-check + make lint
Build stage: standard Go image runs make test + make build
COPY --from=lint /src/go.sum /dev/null creates BuildKit stage dependency (without this, lint is silently skipped)
All images pinned by sha256 per REPO_POLICIES
Reference: sneak/upaas Dockerfile

Tracked from sdlc-manager#6.
