feat: v4.0.0 大版本升级 - SQLite3 + ReAct Agent
- P0: 存储层 IndexedDB → SQLite3 (better-sqlite3)，7张表 + FTS5全文搜索 - P1: Agent Engine 升级为 ReAct 模式（思考→行动→观察→反思） - P2: 新增 4 个工具（memory_search, memory_add, session_list, session_read） - P3: 上下文管理器（滑动窗口 + 摘要压缩 + 记忆注入） - P4: UI 改版（ReAct 执行面板样式 + 思考过程卡片） - P5: IndexedDB → SQLite 数据迁移支持 - MAX_LOOPS 10→15, MAX_LOOP_TIME 5min→10min, 错误自动重试 2 次
