Pin all images by sha256 digest and restructure for the standard split-stage pattern. - Lint stage: golangci/golangci-lint:v1.64.8 pinned by sha256 - Test stage: golang:1.22 pinned by sha256, depends on lint via COPY - Final stage: golang:1.22 pinned by sha256 - COPY --from=lint forces BuildKit to execute the lint stage
