* 新功能： - 支持在线 Embeddings：zhipu-api, qwen-api, minimax-api, qianfan-api - API 增加 /other/embed_texts 接口 - init_database.py 增加 --embed-model 参数，可以指定使用的嵌入模型（本地或在线均可） 问题修复： - API 中 list_config_models 会删除 ONLINE_LLM_MODEL 中的敏感信息，导致第二轮API请求错误 开发者： - 优化 kb_service 中 Embeddings 操作： - 统一加载接口： server.utils.load_embeddings，利用全局缓存避免各处 Embeddings 传参 - 统一文本嵌入接口：server.embedding_api.[embed_texts, embed_documents]
