ci: run just test (fmt + lint + race tests) instead of go test alone (#17)

The Go workflow only ran `go build` + `go test -v ./...`, missing
the gofumpt fmt-check, golines length-check, and golangci-lint
that `just test` runs locally. PR #11 in the meshx sibling repo
landed lint failures because of the same gap; tightening this
here too before it bites.

Add `just` setup + `just fetch` to pull the shared osapi-justfiles,
then run `just test` as the canonical pipeline. Same flow developers
run locally; one source of truth.

go.mod / go.sum pick up the tool-dependency entries `just test`
registers (gofumpt, golines, golangci-lint, gocover-cobertura).
