feat: v0.4.0 四阶段迭代 — 安全加固 + 工程基线 + 架构重构 + 双 Provider 扩展
P0 安全修复: - API Key 加密存储（safeStorage 密钥链，版本化前缀，历史明文平滑兼容） - 间接提示注入防护（SecurityScanHook 工具结果深扫描，网络工具脱敏/本地工具警示分级） - error:report IPC 断链修复（渲染进程错误上报落 electron-log + 审计） - abort 信号贯通工具层（run_command/dev-tools 子进程随会话中断终止） - run_command 沙箱加固（cd 系统目录/敏感文件读取拦截 + chcp 前缀剥离防解析退化） - .env 真实生效（dotenv 回退加载，应用内配置优先） P1 工程基础: - ESLint 9 flat config + 全部 34 条存量 warnings 清零（零容忍基线） - 测试基线 118 用例 11 文件（token/文件防护/权限/沙箱/注入/命令/引擎/注册表/审计链/摘要分层） - test:electron 双模式（ELECTRON_RUN_AS_NODE 跑 Electron ABI，SQLite 套件全执行） - SessionRecorder 多会话隔离 + 9 种 TRACE 事件补全（含最终轮 iteration_end） - Provider 故障转移（重试耗尽/不可重试一次性切换 fallback + 前端通知） - MCP 真就绪（等待全部连接完成再广播 tools:ready） - SLO/HealthChecker 真实接入（60s 巡检 + 托盘状态） - CONFIG_DEFAULTS 单一来源（消除 SEED 双源漂移） P2 架构升级: - handlers.ts 1940 行拆分为 13 个 IPC 域模块（防重入注册 + 多窗口广播） - AgentEngineManager 每会话独立引擎（LRU 30 + adapter 工厂隔离 abort 信号） - TaskOrchestrator EngineProvider 改造 + abortByParent 联动中断 SubAgent - 会话摘要分层上下文（session_summaries 滚动摘要 + 截断游标清理防因果污染） - 消息编辑重发/重新生成（truncateAfter IPC + store 动作 + UI） - Markdown 导出 / WebSearch 并行抓取（并发 3）/ 记忆 TF 缓存 / 版本构建期注入 P3 能力扩展: - OpenAI Adapter（o 系列推理模型 reasoning_effort/max_completion_tokens） - Anthropic Adapter（原生 Messages API：tool_use 块/角色合并/thinking budget/图片 base64/SSE 事件机） - 设置页/Onboarding 六 Provider 全链路接入
