test: mandatory hermetic CLI integration suite + CI gate

The CLI had thin coverage (validateResourceName + 3 provision tests). A CLI
change could silently break provisioning, `up` reconcile, auth, or flag
parsing with nothing catching it. This makes CLI integration testing a
hard, automated gate.

What's added:
- cmd/testapi_test.go: a stateful in-process mock of the agent API,
  emulating the documented openapi.json contract (provision endpoints,
  resource list, credentials, delete, auth/cli). Stateful so the suite can
  PROVE resources are torn down.
- cmd/integration_test.go: 22 end-to-end tests driving the real cobra
  command tree exactly as a shell would — db/cache/nosql/queue new, up
  (+ --dry-run/--emit-env/--env/--file/idempotent reconcile/webhook),
  resources, status, whoami/login/logout, unknown-command, --help. Asserts
  exit codes, stdout/stderr shape, error handling, the resolved-env default
  (empty env -> "development", CLAUDE.md rule 11), and auth handling.
- Resource-cleanup is MANDATORY: every provisioning test defers a per-token
  DELETE, and a suite-level sweep in t.Cleanup FAILS the run if any resource
  is left on the mock. Verified the sweep fires on a deliberate leak.
- cmd/livesmoke_test.go: optional `livesmoke`-tagged live-prod smoke test,
  off by default, provision-then-teardown with mandatory defer cleanup.
- Makefile: `make test` / `make ci` — the local gate is identical to CI.
- .github/workflows/ci.yml: now watches `master` (was `main` only — the
  repo's default branch is master, so CI never actually ran). Runs the
  hermetic suite under -race on every push/PR; a failure blocks.

The whole hermetic suite runs with zero network access.
