/**
 * Jina AI Provider Adapter.
 *
 * Implements Search, Reader, Research, Quota, and Diagnostics capabilities for Jina AI.
 *
 * Field mapping (Jina API → Provider-neutral):
 *   Search (s.jina.ai):
 *     data[].title       -> title
 *     data[].url         -> url
 *     data[].description -> summary (fallback: content)
 *     data[].publishedTime -> date
 *   Reader (r.jina.ai):
 *     data.title         -> title
 *     data.url           -> finalUrl
 *     data.content       -> content (markdown mode)
 *     data.text          -> content (text mode; 8J.2)
 *   Research (deepsearch.jina.ai):
 *     choices[0].message.content -> report
 *     annotations[].url_citation -> sources[]
 *
 * Jina capability-aware credential model (8J.1):
 * - Reader (r.jina.ai) is keyless — available without JINA_API_KEY.
 * - Search (s.jina.ai), Research (deepsearch.jina.ai), Quota, and
 *   Diagnostics require JINA_API_KEY. The credential fingerprint hashes
 *   `"keyless"` when absent (Reader still works; others fail-closed at
 *   preflight).
