After PR #184 and #192 moved managed-embeddings URL resolution to the
CLI project boundary and made `ktx setup` persist `ktx.yaml` without a
`base_url`, the status command still treated the empty value as
misconfiguration and printed "no base_url configured", dragging the
verdict down to "Partially ready — embedding credentials missing".
Update `buildEmbeddingsStatus` to recognize the managed-daemon
convention and report it as ok. Add a `status-project.test.ts` covering
the explicit-url, omitted, empty-string, and openai-missing-key paths.
