release: v0.3.2 — 质量加固 + SQL扩展 + 表达式 + 并发同步
v0.2.6 质量加固: - 修复 AriaEngine 二级索引 SSTable 互相覆盖(命名空间隔离) - 修复 LSM 多版本读取顺序错误 + MergeIterator 取最新来源 - 重写 LZ4 压缩器(往返一致性 + 缓冲区溢出) - sstableCache LRU 上限 + 预加载兜底(BufferPool 配置生效) - 修复 React/Vue 集成 import type 运行时 bug + exports 子路径 - 新增 38 个测试(LZ4往返/Crypto/集成), 删除伪测试 v0.3.0 SQL 功能扩展: - 多语句 parseAll + 事务语句 BEGIN/COMMIT/ROLLBACK - INSERT INTO ... SELECT + UNION/UNION ALL + EXISTS 关联子查询 - CREATE/DROP INDEX 五引擎实现 + 别名 WHERE 修复 - benchmark 页面 + 36 个新测试 v0.3.1 表达式与性能: - CASE WHEN 表达式(SELECT 列/WHERE/聚合) - JOIN + 关联子查询逐行绑定 - WAL 批量组提交(写放大 O(N)→O(1)) - 修复 pending frozen 可见性 + flush 缓存竞争 v0.3.2 并发: - CASE WHEN 用于 WHERE/聚合 + JOIN 哈希连接 - 多标签页同步(multiTabSync + BroadcastChannel) - IndexedDB schema 持久化(reopen 后表结构恢复) - 修复 where-matcher 顶层 $not - 修复 CJS 产物 .js 被 ESM 解析(exports 空) — .cjs 后缀 + exports 修正 - 836 测试 / 44 套件 / 81.0% 覆盖率

* React 集成 hooks 测试（v0.2.6 补强）
|
||||
* @module tests/integrations/react
|
||||
*
|
||||
* 项目零运行时依赖（react 为 peer dependency），
|
||||
* 使用最小 React mock 验证 hooks 的真实逻辑：
|
||||
* - mount 时执行查询并更新状态
|
||||
* - 错误路径
|
||||
* - refresh 重新执行
|
||||
* - 表名校验（SQL 注入防护）
