v0.1.2: 全项目代码审查修复 + 子代理编排器 + 上下文压缩 + 并行工具执行

后端修复: Ollama adapter 移除死代码/修复超时硬编码/iteration硬编码/pullModel无超时/流异常断开补发DONE; SSE解析器支持非字符串arguments; Sandbox fail-closed安全加固; IPC移除未使用变量新增功能: TaskOrchestrator子任务编排器; DelegateTaskTool委派工具; Agent Loop并行工具执行; 上下文自动压缩; 记忆检索注入System Prompt 前端修复: useAgentStream text_delta thought累积bug; 工具调用状态正确流转; 修复重复stateChange事件; TraceStep.thought正确填充
