P1 Missing JSON provider registration

This registers vispark as a JSON-configured OpenAI-compatible provider, but there is no corresponding entry in litellm/llms/openai_like/providers.json. The shared JSON provider path therefore cannot supply Vispark's default base URL or environment-backed credentials. Calls that rely on those provider defaults can target the wrong endpoint or fail authentication. This also violates the repository directive that new OpenAI-compatible integrations follow the established provider contribution pattern.

Rule Used: Block new LLM Provider integrations if they're openai compatible and don't follow https://docs.litellm.ai/docs/contributing/adding_openai_compatible_providers (source)
