/**
 * Jina AI Diagnostics Capability.
 *
 * Probes Jina AI connectivity with a lightweight probe request.
 *
 * The probe calls the Search endpoint (s.jina.ai), which requires
 * `JINA_API_KEY` (8J.1). Without a key the probe is skipped with a
 * `ConfigurationError` so the Doctor reports the correct reason instead
 * of a misleading 401 from the network.
