/**
 * Regression test for #2826 — NOUS-RESEARCH provider always returns 404 Not Found
 *
 * `nous-research` uses `executor: "default"`. `DefaultExecutor.buildUrl()`'s default
 * switch case returns `config.baseUrl` verbatim. Without `/chat/completions` appended
 * every outbound request hits `/v1` and gets a 404.
 *
 * Fix: set `baseUrl` in providerRegistry.ts to include `/chat/completions`.
