test(smoke): end-to-end coverage for SecretBackend, Llm, infer proxy, project-llm-ref

Covers the Phase 0-4 CLI contract against live mcpd. Matches the existing
mcptoken.smoke pattern: skip gracefully on unreachable /healthz, cleanup
fixtures in afterAll, use --direct to bypass mcplocal for admin operations.

- secretbackend.smoke.test.ts
  · seeded plaintext default exists + isDefault
  · create/describe/delete round-trip
  · refuses to delete the default backend (409 shape)
  · get -o yaml output starts with `kind: secretbackend` (apply-compatible)

- llm.smoke.test.ts
  · create secret + llm with --api-key-ref, verify describe hides the
    raw value but surfaces secret://name/key
  · yaml round-trip: get -o yaml > file → amend → apply -f → describe shows change
  · deleting the llm leaves the underlying Secret intact (onDelete: SetNull)

- llm-infer.smoke.test.ts
  · 404 for unknown name, 400 for missing messages
  · 5xx when upstream url is unreachable (proxy returns a structured error)
  · opt-in happy-path gated on LLM_INFER_SMOKE_REAL=1 + LLM_INFER_SMOKE_LLM=<name>
    so CI doesn't need a real provider key

- project-llm-ref.smoke.test.ts
  · describe project with --llm <registered> — no warning
  · describe project with --llm <nonexistent> — shows "warning: …registry default"
  · describe project with --llm none — explicit disable, no warning

These require PRs #51-55 to be merged and fulldeploy.sh run before they'll
find the new endpoints on live mcpd. Until then they skip or fail with
"Not Found". Unit tests for the same code paths (1853 total) continue to
pass against mocks.

+/**
+ * Smoke tests: SecretBackend CRUD against live mcpd.
+ *
+ * Exercises the Phase 0 CLI contract end-to-end:
+ *   1. `mcpctl get secretbackends` — the seeded `default` (plaintext) row exists
+ *      and is marked isDefault.
+ *   2. `mcpctl create secretbackend <name> --type plaintext` — create + list.
+ *   3. `mcpctl describe secretbackend <name>` — sectioned output; config
+ *      values that look like credentials are masked.
+ *   4. `mcpctl delete secretbackend default` — fails with 409 (cannot delete
+ *      the default row).
+ *   5. Cleanup: delete the test row; confirm it's gone.
+ *
+ * Target: mcpd direct (not mcplocal). We use `--direct` so the CLI bypasses
+ * mcplocal and hits mcpd at the configured URL. If mcpd is unreachable we
+ * skip with a clear message — same pattern as the mcptoken smoke.
+ *
+ * Run with: pnpm test:smoke
