nullkey bb592a59a6 feat(cli): contract test suite + dependabot (PR-8)
cli/acceptance/contract/:
  envelope_test.go    — 16 envelope golden cases (9 commands × {success/error
                        variants}; 3 cases dropped with rationale: doctor.success
                        non-offline has unstable timing detail; auth_login.* needs
                        stdin/keyring scaffold deferred to v0.2; context_use.error
                        needs leaf-local --json deferred to follow-up)
  errorcodes_test.go  — single-direction AST scan of cli/cmd/ extracting first
                        arg of cmdutil.NewError / cmdutil.Wrapf calls;
                        ClassifyHTTPError dynamic-classify bridged via
                        cmdutil.ClassifyHTTPErrorOutputs() per spec §4.3.
  testdata/envelopes/ — 16 JSON golden files

helpers_test.go (PR-6 scaffold) extended:
  runCmd now wires cobra Out/Err sinks (version uses c.OutOrStdout) AND
  replicates cmd.Execute()'s error-envelope path so error-case goldens are
  populated. Without this, every error scenario's golden was 0 bytes.

cli/cmd/root.go: mapCobraError → MapCobraError, wantsJSONOutput → WantsJSONOutput
                 (exported so the contract test helper can replicate Execute()'s
                 envelope-printing path without calling Execute() itself).
                 root_test.go updated to use new exported names.

.github/dependabot.yml (新增):gomod /cli + github-actions weekly,gh-style
                              ignore semver-major to avoid noise. Open-source
                              dependency safety,independent of release cadence.

v0.1 不发布到任何分发平台 (release infra 推迟到发布窗口 milestone)。
