+- **feat(providers):** expanded the NanoGPT (`nano-gpt.com`) upstream provider from chat-only to the full OpenAI-compatible endpoint surface: audio transcriptions (`/api/v1/audio/transcriptions`), audio speech (`/api/v1/audio/speech`), video generation (`/api/v1/video/generations`), embeddings (`/v1/embeddings`), and the Responses API (`responsesBaseUrl` → `/api/v1/responses`) ([#9322](https://github.com/diegosouzapw/OmniRoute/issues/9322))
