修复: DeepSeek 400 全量扫描 + 队列 per-conv 隔离

- openai_compat: 扫描所有 assistant 消息剥离 orphan tool_calls（原仅查末条）
- queue 加 conversationId 字段，按会话精准 drain
- regenerate/editMessage 只清本会话排队消息
- newConversation 保留旧会话排队消息
- AiError 只清出错会话的队列项

+
+## 动词词表
+
+| 动词 | 使用场景 |
+|------|---------|
+| `新增` | 新功能、新特性、新文件 |
+| `修复` | Bug 修复、问题修正 |
+| `更新` | 文档更新、配置变更、依赖升级、非功能性的已有内容修改 |
+| `重构` | 代码重构（行为不变的结构调整） |
+| `删除` | 移除功能、删除文件 |
+| `优化` | 性能优化、体验改进 |
+| `合并` | 分支合并 |
+
+## 规范要求
+
+1. **动词 + 冒号 + 空格**：`修复: 审批按钮永久转圈`
+2. **主题行不超过 72 字符**
+3. **主语用中文**，描述清楚改动内容
+4. **不要用内部代号**：禁止 Batch/P1/P2/L1/F-XX 等代号
+5. **不要用分隔线**：禁止 `---` 或 `===` 等装饰线
+6. **不要写无意义提交**：如"更新"、"修复"、"提交"等无法看出内容的单字提交
+7. **改动较多的提交**：主题行概括后，空一行用列表展开具体条目
+8. **文档和代码合并提交**：文档更新和对应代码改动放在同一个提交中，不分散
+
+## 示例
+
+```
+修复: 审批按钮永久转圈和等待计数不停
+```
+
+```
+新增: 文件浏览器增强(窗口分离/Git 变更/行号/Diff/分页提交历史)
+
+- 窗口分离: FileExplorer 可弹出独立 Tauri 窗口
+- 行号显示: 文件预览左侧显示行号列
+- Diff 视图: 有 Git 变更的文件可切换 diff 红绿视图
+- 提交详情: 点击提交查看变更文件列表及文件级 diff
+- 中文编码修复: git 命令注入 LC_ALL 环境变量

+# DevFlow 开发规则
+
+## 技术栈
+
+- 桌面端: Tauri v2 + Vue 3 + TypeScript + Pinia
+- 后端: Rust Workspace (8 crate) / SQLite
+- 包管理: bun (前端) / cargo (Rust)
+- 路径: `E:/wk-lab/devflow`
+
+## 架构原则
+
+1. **治本不治标**：修复问题时找到根因，不做表面补丁
+2. **DRY 原则**：不重复代码，抽象出可复用逻辑
+3. **长远考虑**：不追求局部最优，考虑整体架构演进
+4. **修改收敛**：同类改动合并到一个批次提交，不零散提交
+
+## 代码规范
+
+1. **Rust 后端**：提交前运行 `cd src-tauri && cargo check`
+2. **前端 TypeScript/Vue**：提交前运行 `npx vue-tsc --noEmit`
+3. **完整构建**：提交前运行 `npx vite build`（验证构建不报错）
+4. **TypeScript 文件名**：camelCase（`fileExplorer.ts`）
+5. **Vue 组件文件名**：PascalCase（`FileExplorer.vue`）
+
+## i18n
+
+- 中英文双语言同步：`src/i18n/en/` 和 `src/i18n/zh-CN/`
+- 新增组件时同时添加对应语言的翻译文件
+- 国际化文件自动聚合（`src/i18n/*/index.ts` 自动导入所有模块文件）

+ * 跨端适配:
+ * - 微信小程序:uni.connectSocket(微信原生 API,非浏览器 WebSocket)
+ * - H5:uni.connectSocket 封装浏览器 WebSocket
+ * - 统一经 uni API 封装,业务层不直接 new WebSocket
+ *
+ * 连接生命周期(P0/P1 审计后重构,根本性,非补丁):
+ * - 所有"建连"经 reconnectNow() 幂等入口:clear 退避 timer + cleanup + openSocket
+ *   connect()/resumeIfDisconnected()/scheduleReconnect 回调全部经此,杜绝双连竞态 + socket 泄漏
+ * - openSocket() 幂等:首行 destroySocket 残留 socket,保证 this.socket 引用唯一
+ * - destroySocket(task):显式注销 onOpen/onMessage/onClose/onError(覆盖空函数,微信无 offXxx)
+ *   + close,防旧 socket 闭包回调污染新连接(单例 this 句柄被多 socket 捕获)
+ * - cleanup() 彻底化:destroySocket + 停心跳 + 清所有 timer + 清 pendingQueue
+ *   清队列防跨连接/跨会话陈旧命令补发(旧命令上下文已失效)
+ * - 超时三重兜底:连接超时(onOpen 未到)/握手超时(hello_ack 丢失,>relay 10s)/
+ *   onError 兜底(微信 socket onError 不保证 onClose 跟随,DNS/TLS/域名未加白场景)
+ * - 心跳活性检测:lastInboundAt + 2x 间隔判定半开死连接(NAT 超时/网络切换)
+ * - pendingQueue 上限 + TTL:防握手永卡时无限堆积内存泄漏
+ *
+ * 重连:指数退避(baseDelay * 2^min(n,6),封顶 maxDelay,带随机抖动)
+ * 心跳:固定间隔发 ControlMessage{control_kind:'ping'},防空闲断开 + 在线状态
+ * JSON 透传:入站解析为 BroadcastMessage,payload 是 AiChatEvent JSON
