feat: v0.7.2 安全收口 · 断链接线 · 观测补洞 — 230 用例扩充与全量回归

P1 修复面收口: /clear 全链路根治(前端清空联动 DB messages+摘要游标+TRACE 快照,
IPC 语义改"操作完成"; 流式中拒绝); web_browser open 补 SSRF 校验(Chromium 旁路关闭,
与 web_fetch/http_request 同源 validateSSRF); MCP 工具结果纳入注入扫描(mcp_* 前缀
按网络来源同级 full 模式, 收敛 resolveScanMode 单点); Trace 落库/入 store 双重瘦身
(tool_result base64/超长字段剥离, metadata 防 MB 级膨胀); 文本附件 512KB 闸门
(file.slice 首段读取+truncated 标志随消息持久化+主进程附件提示感知截断);
单实例锁(requestSingleInstanceLock + second-instance 聚焦已有窗口)

P2 安全纵深: ConfirmationHook 多窗口化(确认请求/超时提示改全窗口广播,
getAllWindows 空时回退 mainWindow, fail-closed 判定升级双通道); mcp_servers.headers
全链路接线(safeParseHeaders 容错解析+SSE/StreamableHTTP requestInit 注入+IPC 逐项
校验+设置页 JSON 输入, 远程 MCP 鉴权头可用)

P3 断链接线: llm:listModels IPC(六家 adapter 动态模型发现首次接线, 配置完整性
前置校验); Ollama pullModel IPC+设置页下载卡片(进度/取消/能力徽标, v0.7.0 死代码
激活); 后台会话运行指示(sessionRunStates 图+Sidebar 状态点, 多会话并发可见);
IR 卫生(移除 THINKING_START/END 死枚举, constraints 标注预留)

P4 质量与文档: i18n 第二阶段(确认弹框/侧栏/状态栏/AgentMonitor/终止原因出层,
外观设置 zh-CN/en-US 切换, ui.locale 持久化, 渲染时求值规避异步注册); README/D1
文档对齐(http_request 风险等级/用例数/实现状态注记); 版本号 0.7.2

测试: 507 → 737 用例(+230, 11 个新文件)。覆盖补齐: context-builder/consolidator/
orchestrator/workspace.service/session-recorder/config-layering/secure-config/
network-proxy + IPC mcp/tasks/memory/app/data 域 + 渲染层 store 与流事件管线纯函数。
测试驱动修复: workspace.appendMemory 中文分区 \b 词边界失效(JS \b 不含 CJK),
固化条目恒追加文件末尾产生重复分区头 → (?=\n|$) 前瞻断言根治

回归: typecheck 双端 0 错误; ESLint 0/0; 系统 Node 687 通过 50 跳过;
Electron ABI 全量 737/737 零跳过
