refactor(chain): 处理链功能域 mixin 化，清理未使用导入并根治兼容层循环导入

- ChainBase 拆分为 RecognitionMixin/MessageProcessingMixin/NotificationMixin - TransferChain 拆分为 7 个功能 mixin（_mixins.py），SubscribeChain 音乐订阅域拆出 _music.py - 斜杠命令交互四件套收敛为 InteractionChainMixin 委托，会话管理器移至 application 层，chain 层不再 re-export - 模块基础类收敛到 app/modules/_base（notification/mediaserver 语义重命名） - 清理 app/chain/__init__.py 24 个未使用导入，修正 49 处测试 patch 目标到实际命名空间 - 兼容层 legacy 符号不再并入 __all__，根治 schemas 初始化反向拉起 application.transfer 的循环导入 - 修复 bangumi 集数为字符串时 set_bangumi_info 抛 TypeError - 新增重复代码等架构门禁测试；capability 清单校验排除下划线内部目录

+"""插件 API 动态路由服务。
+
+把插件 API 的动态注册/移除从 HTTP 端点层下沉到 application 层：
+FastAPI 实例由组合根（factory 创建应用后）注入，端点与 Agent 工具
+统一经本模块操作路由，消除 api.endpoints 对 factory 的反向依赖。
+
+依赖方向：
+
+    api.endpoints.plugin / agent.tools -> application.plugins <- factory（注入实例）
