Agent 注册链

本文说明 AgentRegisterFactory.launch(registerContext) 内部的注册链。注册链的职责是基于启动层已经构建好的 AgentRegisterContext，完成组件、模块、Capability、生命周期方法和关闭方法的注册。

AgentRegisterContext 是注册链上下文。它持有 Reflections 扫描器，以及供各阶段读写的 ComponentFactoryContext、CapabilityFactoryContext 和全局 AgentContext。

AgentContext

AgentContext 是注册链的主要产物。它不是单轮对话上下文，而是运行时组件注册结果和关闭逻辑的集中容器。
