refactor(db): 重构数据库构建器以支持JOIN参数传递并删除示例配置文件

- 修改 Get 方法以根据是否存在 JOIN 来构建参数结构
- 修改 Count 方法以根据是否存在 JOIN 来传递参数
- 修改 Select 方法以根据是否存在 JOIN 来构建参数结构
- 在 where.go 中添加对 [##] 键的支持以直接添加 SQL 片段
- 删除 example/config/admin.json 配置文件
- 删除 example/config/config.json 配置文件
- 删除 example/config/configNote.json 配置文件
- 删除 example/config/rule.json 配置文件
- 删除 example/benchmark_test.go 压测文件
- 重构 example/main.go 文件，添加完整的 HoTimeDB 功能测试套件
- 添加调试日志功能以跟踪数据库操作流程
