Removes testify + davecgh/go-spew + pmezard/go-difflib from go.mod; rewrites assert/require calls across 13 _test.go files (buffer/daemon/errors/exec/global/health/pidfile/process/program/ registry/runner/service + pkg/api/provider) to stdlib t.Fatalf patterns. go vet + go test all clean (GOWORK=off). Closes tasks.lthn.sh/view.php?id=719 Co-authored-by: Codex <noreply@openai.com> Via-codex-lane: Cyclops-719 dispatch (haiku forwarder, ~17min lane)
