Replace the service-lifecycle init script with a lean Go-native default workflow. Running the container with no arguments now automatically formats, vets, tests, and builds the mounted project. - rootfs/usr/local/etc/docker/init.d/00-go.sh: stripped from 979 lines of daemon-lifecycle boilerplate to 3 lines that export CONTAINER_INIT=yes and SERVICE_USES_PID=no, telling the init framework this is a configuration-only container (no daemon, no keep-alive loop) - rootfs/usr/local/bin/go-workflow: new script — runs the canonical Go workflow in order: go mod tidy → gofmt -w . → go vet ./... → go test ./... → go build ./...; exits 1 with a clear usage message if no go.mod is found in /app - rootfs/usr/local/bin/entrypoint.sh: no-args path in both the init block and the * case now exec go-workflow instead of __no_exit; verified: default workflow, explicit commands, sh -c passthrough, and missing go.mod error all behave correctly - README.md: document the default workflow prominently; update one-shot examples; add golangci-lint --timeout note; add tail null long-running pattern README.md rootfs/usr/local/bin/entrypoint.sh rootfs/usr/local/bin/go-workflow rootfs/usr/local/etc/docker/init.d/00-go.sh
