feat: v0.7.0 四阶段全量迭代 — 修复面收口 · 安全纵深 · 架构还债 · 能力演进

P1 修复面收口: v0.6.3 截断自愈推全量(Anthropic/Ollama/非流式/引擎兜底); SSE 上游错误帧检测进重试通道;
clearMessages 摘要游标根治; truncateResult 内联图片白名单统一; 前端四 bug(确认弹窗锁死/MemoryViewer/
Virtuoso Footer/abort 尾部过滤) + reasoning 缓冲跨迭代污染; 托盘通知过滤与新建会话死链接线

P2 安全纵深: MCP 审批闭环(ConfirmationHook×PolicyEngine 联动+重名拒注册); SSRF 收敛 ssrf-guard 共享模块
(web_fetch 双通道校验+重定向终态复检); Electron 加固(preload CJS 化→sandbox:true/CSP/权限白名单/will-navigate);
run_command cmd.exe 白名单通道元字符守门; diff_viewer 10MB 预检; Anthropic thinking 预算下限; Agnes 思考显式关闭

P3 架构还债: OpenAICompatibleAdapter 中间基类收敛四家样板; 错误分类单轨化(删 mapError/getFetchSignal,
超时显式 ETIMEDOUT); PRAGMA user_version 迁移版本化; 死代码清理专项(cn.ts/SHORTCUTS/ContextMenu 分支/
getWindowState/modifiedArgs/sandbox 空壳); i18next 引入; a11y 第一轮; SearXNG 页批量草稿模型统一

P4 能力演进: Ollama pull 可取消/capabilities 探测/num_ctx 实测缓存; UpdateService feed 比对式自动更新
(app:updateCheck IPC + StatusBar 入口); MiMo providerOptions(web_search 服务端工具/strict JSON);
web_fetch extract_mode=markdown(turndown); network.proxyUrl 全局代理(Chromium sessions+undici dispatcher)

测试: 264 → 507 用例(Electron ABI 全绿零跳过), 覆盖引擎压缩管线/重试竞速/MEMORY.md 闸门/file_editor 五操作/
filesystem 七工具实体夹具/git 真实仓库/SSE 错误帧/全线截断自愈/Provider 请求形态矩阵/SSRF 表测/钩子分级矩阵/
OutputValidator 全量/SLO 指标/MCP 安全纯函数/task_manager 链路/渲染层纯域/i18n 桥契约

+ * 流式上游错误帧 + 全线截断自愈测试（v0.6.4）

+ * 1. 错误帧黑洞 —— OpenAI 兼容网关中途发送的 `{"error":{...}}` 数据帧被解析器
+ *    整帧吞掉（零日志），任何上游错误都伪装成"干净的空回复 + 正常 DONE"，
+ *    且以普通事件而非异常出现，绕过引擎的重试/故障转移通道。
+ * 2. 截断自愈只修了 OpenAI 共享层 —— v0.6.3 的 _truncatedArguments 修复未覆盖：
+ *    - Anthropic：content_block_stop 解析失败静默 args={}；断流时未完成块整体蒸发
+ *    - Ollama：NDJSON 坏参抛错落入外层 catch，工具调用丢弃且同 chunk USAGE/DONE 被跳过
+ *    - 非流式 parseOpenAICompatibleResponse：坏参仍静默 {}
+ *    - 引擎兜底缓冲 finalizeToolCallsFromBuffer：坏参静默 {}
+ *
+ * 本文件锁定以下契约：
+ * A. 上游错误帧 → 抛出携带归一化 status 的 SseUpstreamError（可驱动重试判定）
+ * B. finish_reason=content_filter → ContentFilterError（终态、不重试）
+ * C. data:{无空格} 变体正常解析
+ * D. 非流式/Ollama/Anthropic 截断参数统一转 _truncatedArguments 自愈载荷
+ * E. Ollama 坏参不再吞掉同 chunk 的 done/USAGE 处理
+ * F. Anthropic 断流时未完成 tool_use 块 flush 为自愈调用 + DONE
