MINIMAX_ANTHROPIC_BASE_URLis read here but isn't documented anywhere (.env.example,README.md,DOCUMENTATION.md, or theprovider_config.pyextra_varslist), unlike its OpenAI counterpartMINIMAX_API_BASE. The naming is also asymmetric (MINIMAX_API_BASEvsMINIMAX_ANTHROPIC_BASE_URL).Either document both fallback vars consistently, or drop them in favor of the four region/protocol-specific vars that are already documented.
