feat: 升级至 v0.3.15 — MiMo 多模态 + 工作空间数据库继承 + 引导窗口上下文配置 + TS 错误修复

- feat(mimo): 适配器支持图片输入，将 images 转为 OpenAI 兼容 content parts 数组
- feat(workspace): 切换工作空间时支持继承数据库 agent.db（SQLite backup API 原子导出，自动 checkpoint WAL）
- feat(onboarding): 引导弹窗 LLM 配置加上下文长度字段（DeepSeek/Agnes=1000000、MiMo=131072、Ollama=null）
- fix(types): 修复 16 个 TypeScript 编译错误（setConfigLoaded 接口声明、10 个 IPC 返回类型加 error 字段、MUI TextField readOnly slot 迁移）
- chore(workspace): 移除死代码 traces 目录（trace 数据实际存储于数据库 sessions.metadata 字段，traces 目录从未被任何代码读写）
- docs(mimo): API 文档补充多模态输入章节和 curl/Python 代码示例
- chore: 版本号 0.3.14 → 0.3.15
