feat: v0.2.0 AriaEngine 自研存储引擎
- 新增 AriaEngine: LSM-Tree 页面式存储引擎，19 个模块，~3500 行 TS - page/: Slotted Page 格式 (header/slot/tuple/format) + CRC32 - buffer/: Buffer Pool (LRU 缓存 + 驱逐策略) - index/: LSM-Tree (MemTable 红黑树 + SSTable + Bloom Filter + Merge Iterator) - wal/: WAL 日志 (二进制格式) + Checkpoint 管理 - transaction/: MVCC 版本链 + 快照隔离 - store/: IndexedDB / Memory 双后端抽象 - compression/: LZ4 页面压缩 - 完整持久化: Schema 自动保存、SSTable 元数据管理、WAL 恢复 - 事务感知 CRUD: insert/update/delete 在事务中缓冲到 snapshot - mode: 'aria' 激活自研引擎 - 新增 7 个测试文件，测试数 318 → 524，套件 20 → 27 - aria-page.test.ts (32 tests): Page 格式单元测试 - aria-index.test.ts (26 tests): Bloom Filter + MemTable - aria-sstable.test.ts (9 tests): SSTable Builder + Reader - aria-buffer.test.ts (25 tests): LRU + Eviction + Buffer Pool - aria-wal-mvcc.test.ts (22 tests): WAL 编解码 + MVCC 事务 - aria-compress.test.ts (11 tests): LZ4 + Merge Iterator - aria.test.ts (80 tests): AriaEngine 集成 + 边界测试 - Bug 修复: LRUList size 跟踪、WAL 缓冲区越界、ColumnEncoding 导入 - 全面更新 README.md + site/ 站点文件 (index/docs/demo)
