重构代码结构并添加完整功能

Browse Source 
主要改动：
- 重构目录结构：合并子目录到根目录，简化项目结构
- 添加完整的查询 API：支持复杂条件查询、字段选择、游标模式
- 实现 LSM-Tree Compaction：7层结构、Score-based策略、后台异步合并
- 添加 Web UI：基于 Lit 的现代化管理界面，支持数据浏览和 Manifest 查看
- 完善文档：添加 README.md 和 examples/webui/README.md

新增功能：
- Query Builder：链式查询 API，支持 Eq/Lt/Gt/In/Between/Contains 等操作符
- Web UI 组件：srdb-app、srdb-table-list、srdb-data-view、srdb-manifest-view 等
- 列选择持久化：自动保存到 localStorage
- 刷新按钮：一键刷新当前视图
- 主题切换：深色/浅色主题支持

代码优化：
- 使用 Go 1.24 新特性：range 7、min()、maps.Copy()、slices.Sort()
- 统一组件命名：所有 Web Components 使用 srdb-* 前缀
- CSS 优化：提取共享样式，减少重复代码
- 清理遗留代码：删除未使用的方法和样式
