fix(crawl4ai): construct the fetch client off the event loop (#7906)
* fix(crawl4ai): construct the fetch client off the event loop

Crawl4AiClient builds an httpx.AsyncClient per fetch, and AsyncClient
construction loads the TLS trust store synchronously: on the agent event
loop that blocks every other request for the CA bundle read. Construct it
through asyncio.to_thread, the same rule the RAGFlow/LightRAG and
You.com/GroundRoute/Webz clients already follow; the request and cleanup
stay on the loop.

* docs(agents): list Crawl4AI among the off-loop HTTPX clients

#7889 extended the same sentence for its providers; keep the named list in
the same change set as the client, and record the clients that still
construct on the loop so the next migration has a checklist.
