Description

Add an API interface for NPCBOT to integrate with the LLM chat model and achieve chat functionality for AI models.
It is necessary to add the most basic prompt word function to the interface configuration to unify the language used in the chat interaction process.

Furthermore, it is also possible to consider using AI chat to execute npcbots commands, achieving some basic interactive operations that were originally implemented through menus.
For example, interactive provision of water, food, and dining tables.

The LLM model framework can consider choosing software that can be deployed on Docker, such as Olama or Xinference.
