// Regression for issue #3136: a `llama-cpp` local provider connection must send
// requests to the user's configured local baseUrl, not OpenAI's API. Before the
// fix, `llama-cpp` was missing from the local-provider case group in buildUrl(),
// so it fell through to the registry/default path and (because llama-cpp is not
// in the registry → DefaultExecutor falls back to PROVIDERS.openai) resolved to
// https://api.openai.com/v1/... — producing OpenAI-worded 401 "no api key" errors.

// baseUrl was set; with an empty one, `this.config.baseUrl` (= PROVIDERS.openai,
// since llama-cpp is not in the open-sse registry) leaked through, producing
// OpenAI-worded "incorrect api key" errors. Now it must fall back to the
// catalog's localDefault (http://127.0.0.1:8080/v1).
