Cloudflare Web Search API (through AI Gateway) as a Perplexed.Search provider.
One endpoint fronts three upstream engines, chosen with :provider:
"ceramic" (Cloudflare's default upstream, long page descriptions),
"linkup" (fast raw results) and "exa" (auto mode, page highlights).
Requests bill at each engine's list price through AI Gateway credits, or
to a provider key stored on the gateway. At most ten results per request.
Needs config :perplexed, cloudflare_account_id: and a
cloudflare_api_token: with Workers AI Read and AI Gateway Read;
cloudflare_gateway_id: defaults to "default".
