featmodel): 添加保存模式选择功能

在模型管理页面中新增保存模式选择功能，用户可以通过下拉菜单选择不同的保存模式（如默认、合并16位、合并4位等）。同时，将保存模型的逻辑抽离到独立的`save_model.py`文件中，以提高代码的可维护性和复用性。

+# 基于文档驱动的自适应编码大模型微调框架
+
+## 简介
+
+### 项目概述
+本项目是一个基于文档驱动的自适应编码大模型微调框架，通过深度解析私有库的文档以及其他资源，生成指令型语料，据此对大语言模型进行针对私有库的微调。
+
+### 核心功能
+- 文档解析与语料生成
+- 大语言模型高效微调
+- 交互式训练与推理界面
+- 训练过程可视化监控
+
+## 技术架构
+
+### 系统架构
+```
+[前端界面] -> [模型微调] -> [数据存储]
+    ↑               ↑             ↑
+    │               │             │
+[Gradio]     [unsloth/QLoRA]  [SQLite/TinyDB]
+```
+
+### 技术栈
+- **前端界面**: Gradio构建的交互式Web界面
+- **模型微调**: 基于unsloth框架的QLoRA高效微调
+- **数据存储**: SQLite(结构化数据) + TinyDB(非结构化数据)
+- **工作流引擎**: LangChain实现文档解析与语料生成
+- **训练监控**: TensorBoard集成
+
+## 功能模块
+
+### 1. 模型管理
+- 支持多种格式的大语言模型加载
+- 模型信息查看与状态管理
+- 模型卸载与内存释放
+
+### 2. 模型推理
+- 对话式交互界面
+- 流式响应输出
+- 历史对话管理
+
+### 3. 模型微调
+- 训练参数配置(学习率、batch size等)
+- LoRA参数配置(秩、alpha等)
+- 训练过程实时监控
+- 训练中断与恢复
+
+### 4. 数据集生成
+- 文档解析与清洗
+- 指令-响应对生成
+- 数据集质量评估
+- 数据集版本管理
+
+## 微调技术
+
+### QLoRA原理
+QLoRA(Quantized Low-Rank Adaptation)是一种高效的大模型微调技术，核心特点包括：
+1. **4-bit量化**: 将预训练模型量化为4-bit表示，大幅减少显存占用
+2. **低秩适配**: 通过低秩矩阵分解(LoRA)实现参数高效更新
+3. **内存优化**: 使用梯度检查点等技术进一步降低显存需求
+
+### 参数配置
+- **学习率**: 建议2e-5到2e-4
+- **LoRA秩**: 控制适配器复杂度(建议16-64)
+- **LoRA Alpha**: 控制适配器更新幅度(通常设为秩的1-2倍)
+
+### 训练监控
+- **TensorBoard集成**: 实时查看损失曲线、学习率等指标
+- **日志记录**: 训练过程详细日志保存
+- **模型检查点**: 定期保存中间权重
+
+## 快速开始
+
+1. 安装依赖:
+```bash
+pip install -r requirements.txt
+```
+
+2. 启动应用:
+```bash
+python main.py
+```
+
+3. 访问Web界面:
