feat(model): introduce rate limiting and guardrail models with typed policy configurations

enhance proxy configuration with structured models for token rate limiting and AI guardrails,
transition policy definitions from dictionary to typed objects, and extend model proxy props
with execution role support; upgrade alibabacloud-agentrun dependency for improved capabilities

为代理配置引入结构化的令牌速率限制和 AI 防护模型，将策略定义从字典类型转为强类型对象，
并在模型代理属性中新增执行角色支持；升级 alibabacloud-agentrun 依赖以提升功能能力
