feat: split Dockerfile into dedicated lint and build stages
- Add dedicated lint stage using pre-built golangci-lint v2.10.1 image
- Move fmt-check and lint from build stage to lint stage for faster feedback
- Remove manual golangci-lint binary download (now handled by lint image)
- Remove curl from build stage dependencies (no longer needed)
- Add COPY --from=lint dependency to force BuildKit to run lint stage
- Build stage now runs only tests and compilation
