// #5420 — Tool-only providers (web search / web fetch) do not expose a model
// listing; their "Import Models" button hits the `400 "does not support models
// listing"` route. The old `-search` suffix heuristic caught `brave-search` but
// missed tool-only providers whose id has no suffix (e.g. `firecrawl`, declared
// `serviceKinds: ["webFetch"]`). This pure helper decides, from the provider id
// plus its resolved serviceKinds, whether to hide model listing — without ever
// hiding an LLM or media provider that genuinely lists models. Leaf module: it
// imports nothing, so it cannot create an import cycle with the page.

/** Service kinds that, on their own, mean the provider lists no models. */

 *  - it declares at least one serviceKind and EVERY declared kind is a tool-only

 *
 * Returns false for an empty `kinds` (most LLM providers declare nothing) and for
 * any provider that has `llm`/image/video/music/tts/stt/embedding.
