- Add lint stage using prebuilt golangci/golangci-lint image for fast feedback on formatting and lint issues - Add build stage using golang:1.24-alpine for tests and compilation (replaces sneak/builder:2022-12-08 which has Go 1.19, too old for go 1.23 modules) - Build stage depends on lint stage via COPY --from=lint to ensure BuildKit runs both stages - All Docker base images pinned by sha256 hash - Add Makefile targets: fmt-check, build, check, hooks - check target runs fmt-check, lint, and test - CI workflow simply runs 'docker build .' which implicitly runs all checks via the Dockerfile stages - Update README with new targets and correct Go version requirement - Remove vendor.tzst/modcache.tzst references from Dockerfile (removed in prior commit)
