/**
 * Kagi Provider Adapter.
 *
 * Implements Search for the Kagi API (GET /api/v1/search, or
 * GET /api/v0/enrich/news when controls.topic === "news").
 *
 * Wire response is `{ meta, data: [...] }`. Only `t === 0` rows with a
 * truthy url are results; `t: 1` rows are related-query suggestions and
 * MUST be dropped (SCHEMA.md — pinned).
 *
 * Field mapping:
 *   item.title      -> title
 *   item.url        -> url
 *   item.snippet    -> summary
 *   item.published  -> date (when present)
 *   source          -> "kagi" (constant)
 *
 * Control mapping (SearchControls → wire):
 *   domain      -> `site:<domain> ` query prefix
 *   topic:news  -> v0 enrich/news endpoint (same q/limit)
 *   recency     -> REJECTED (UnsupportedOptionError)
 *   location    -> REJECTED (UnsupportedOptionError)
 *   contentSize -> REJECTED (UnsupportedOptionError)
 *   type        -> REJECTED (UnsupportedOptionError)
 *
 * Auth is `Authorization: Bot <key>` — Kagi wire truth, not Bearer.
 * Diagnostics probes the same v1 search endpoint with q=scoutline-doctor-probe&limit=1.
