Add configuration files for FastGPT and Xfyun voice services, enhancing LLM service capabilities. Update LLMConfig to include chat_id, variables, detail, and timeout settings. Refactor create_llm_service to support FastGPT integration and adjust pipeline to handle chat_id and greeting prompts. Implement context synchronization for interrupted assistant turns in text streaming.
