// Regression guard for #11060 — Perplexity's /v1/models endpoint lists the
// Agent API catalog (vendor-prefixed ids like "anthropic/claude-fable-5"), but
// chat requests always go to the classic /chat/completions endpoint, which only
// accepts the Sonar family. Without a PROVIDER_MODELS_CONFIG entry, generic
// model import pulled those agent-style ids into the connection's chat model
// list and every routed request failed with 400 "Invalid model". The discovery
// entry must exist and its parseResponse must keep only Sonar-family ids.
