/**
 * Issue #6674 — Add Naga.ac and ChatAnywhere as gpt4free-ecosystem aggregator providers.
 *
 * Verifies both providers are wired end-to-end the same way as the other aggregator
 * gateway providers (g4f-groq, freetheai):
 *   - present in the executor REGISTRY with an OpenAI-compatible shape
 *   - resolvable through getExecutor() (falls through to DefaultExecutor)
 *   - listed in AGGREGATOR_PROVIDER_IDS so they show up in the aggregator category
 *   - has provider metadata (name/website/free-tier note) in the apikey gateway catalog
 *   - Naga.ac allows optional API key (free models); ChatAnywhere requires a key
