工程化（从零到一）: - 新增 Gitea Actions CI（debian-latest）：类型检查 + Lint + 单元测试 + 产物编译验证 - 新增 husky + lint-staged 预提交钩子（lint-staged + typecheck 门禁） - 移除坏脚本 test:e2e（无 Playwright 配置必失败）；prebuild 改用内置 fs.rmSync - 依赖清理：移除死依赖 sql.js(2MB)/@playwright/test，@types/shell-quote 移至 devDependencies 安全加固: - PolicyEngine 频率限制按会话隔离（多会话并发不再互抢配额） - ConfirmationHook 拒绝记忆加 10 分钟 TTL + 恢复询问入口（新增 2 个 IPC 通道） - Windows run_command 白名单工具（git/node/npm/npx/pnpm/yarn/tsc）改走 cmd.exe /c + 参数数组执行，收窄 shell 注入面 - web_search 四引擎 HTML 解析迁移 node-html-parser（结构化主层 + 正则降级） 缺陷修复（测试驱动发现）: - mapError 大小写缺陷：网络错误码永远落入 UNKNOWN 无法触发重试 - 搜狗解析器自我过滤：相对链接补全后又被 sogou.com 过滤导致结果全丢 - 百度复合类名重复收录：class="result c-container" 被双重匹配 测试补齐（113 → 194 用例）: - 新增 5 个测试文件：sse-stream / base-adapter / confirmation-hook / ipc-agent 编排链路 / web-search 解析器 - 覆盖 sendMessage 全分支、SSE 流解析、错误映射、确认钩子竞态/超时/批量审批 体验升级: - OutputValidator 验证结果可见化（VALIDATION 流事件 → 聊天流提示卡） - SettingsModal 巨型组件拆分（1503 行 → 10 个文件，可独立维护） - MessageList 接入 react-virtuoso 真虚拟滚动（千条消息恒定开销） - MCP 新增 streamable HTTP 传输支持（SDK 内置传输 + DB 迁移 6 + UI 双模式）
