Add pre-built golangci/golangci-lint:v1.64.8 image as a separate lint stage for fast lint feedback without rebuilding the entire builder. - Lint stage: installs protobuf-compiler, generates code, runs make lint - Build stage: pins sneak/builder by sha256, removes inline golangci-lint - COPY --from=lint forces BuildKit to execute the lint stage - All images pinned by sha256 digest - Final stage (FROM scratch) unchanged
