完整实现 Swarm 多智能体协作系统

- 新增 CLIPluginAdapter 统一接口 (backend/app/core/agent_adapter.py)
- 新增 LLM 服务层，支持 Anthropic/OpenAI/DeepSeek/Ollama (backend/app/services/llm_service.py)
- 新增 Agent 执行引擎，支持文件锁自动管理 (backend/app/services/agent_executor.py)
- 新增 NativeLLMAgent 原生 LLM 适配器 (backend/app/adapters/native_llm_agent.py)
- 新增进程管理器 (backend/app/services/process_manager.py)
- 新增 Agent 控制 API (backend/app/routers/agents_control.py)
- 新增 WebSocket 实时通信 (backend/app/routers/websocket.py)
- 更新前端 AgentsPage，支持启动/停止 Agent
- 测试通过：Agent 启动、批量操作、栅栏同步
