feat: v4.3 生态扩展 — 诊断系统 + Heartbeat + 子代理 + MCP
新增功能： 1. 🩺 一键诊断系统 - 设置面板添加「一键诊断」按钮 - 检查项：Ollama 连接、模型可用性、模型能力（Tools/Vision/Think）、 SQLite 数据库、技能系统、应用版本信息 - 实时渲染诊断结果，✅/⚠️/❌ 状态标识 2. 💓 Heartbeat 后台检查 - 设置面板添加开关 + 间隔选择（10分/30分/1小时/2小时） - 定时检查 Ollama 连接，异常时系统通知 - 配置持久化到 settings，启动时自动恢复 - startHeartbeat/stopHeartbeat/restoreHeartbeat 三件套 3. 🤖 子代理委派（spawn_task） - 新增 spawn_task 工具（26 个工具） - 子 Agent 独立运行（独立消息上下文，5 轮上限，2 分钟超时） - 不支持工具调用，专注于文本推理任务 - 主 Agent 可传入附加上下文 - 结果返回主 Agent Loop 4. 🔌 MCP Client 框架 - mcp-client.ts: MCP 服务器配置管理（增删改查、启用禁用） - 配置存储在 settings.mcp_servers - 工具注册框架就绪，待主进程 MCP bridge 实现协议通信 新增文件：mcp-client.ts, sub-agent.ts 修改文件：settings-modal.ts, index.html, main.ts, tool-registry.ts
