feat(gendao): 添加代码生成工具用于自动生成DAO层代码

- 实现了完整的gendao命令行工具功能 - 添加了模板文件用于生成DAO、DO、Entity等代码结构 - 集成了数据库表字段映射和类型转换功能 - 支持分片表模式匹配和自定义配置选项 - 实现了代码清理和格式化功能 - 提供了灵活的表名过滤和前缀处理机制

+# GF-Source 自维护代码
+
+这个目录包含了从 GoFrame (GF) 框架复制并修改的 DAO 生成工具源码，已将所有 `gdb` 相关引用替换为项目自定义的 `database` 包。

+
+## 🔧 主要修改
+
+### 1. 数据库接口替换
+- ✅ `github.com/gogf/gf/v2/database/gdb` → `git.magicany.cc/black1552/gin-base/database`
+- ✅ `gdb.DB` → `database.DB`
+- ✅ `gdb.ConfigNode` → `database.ConfigNode`
+- ✅ `gdb.AddConfigNode()` → `database.AddConfigNode()`
+- ✅ `gdb.Instance()` → `database.Instance()`
+- ✅ `g.DB()` → `database.Database()`
+
+### 2. 内部包路径修改
+- ✅ `github.com/gogf/gf/cmd/gf/v2/internal/consts` → `git.magicany.cc/black1552/gin-base/cmd/gf-source/internal/consts`
+- ✅ `github.com/gogf/gf/cmd/gf/v2/internal/utility/mlog` → `git.magicany.cc/black1552/gin-base/cmd/gf-source/internal/utility/mlog`
+- ✅ `github.com/gogf/gf/cmd/gf/v2/internal/utility/utils` → `git.magicany.cc/black1552/gin-base/cmd/gf-source/internal/utility/utils`
+
+### 3. 包名统一
+- ✅ 所有 gendao 相关文件统一为 `package gendao`
+- ✅ 模板文件移至 `templates/` 子目录（避免包名冲突）
+
+## 📦 编译
+
+```bash
+cd cmd/gf-source
+go build .
+```
+
+## ⚠️ 注意事项
+
+1. **这是参考代码**：这个目录主要用于参考 GF 的 DAO 生成逻辑，实际使用的是 `cmd/gin-dao-gen/main.go`
+2. **不要直接导入**：这个子模块有独立的 go.mod，不应该被主项目直接导入
+3. **保持同步**：如果 GF 更新了 DAO 生成逻辑，需要手动同步这些文件并重新应用修改
+
+## 🔄 更新流程
+
+如果需要从 GF 更新代码：
+
+1. 从 `D:\web-object\gf\cmd\gf\internal\cmd\gendao` 复制最新文件
+2. 运行批量替换脚本将 `gdb` 改为 `database`
+3. 运行批量替换脚本将 internal 路径改为本项目路径
+4. 测试编译确保没有错误
+
