Kris 742299cb07 chore: 批量清理报告相关代码并完成多项功能迭代
本次提交包含多维度代码优化与功能增强:
1.  移除报告模块冗余导入与枚举,清理报表相关代码
2.  新增扫码登录支持方法与飞书适配器适配
3.  完善异常日志与健康检查信息
4.  扩展目录、配对管理、能力查询等接口
5.  优化出站管道与事务提交后钩子逻辑
6.  修复飞书消息解析与响应空值问题
7.  重构配置更新与服务账号创建逻辑
8.  统一传输错误分类契约与错误基类扩展

"""微信 iLinkClawBot渠道插件生命周期钩子处理。
实现 ``LifecycleHookHandler`` Protocol管理插件级资源httpx 连接池),
响应宿主生命周期状态变迁。
设计要点:
- LifecycleHandler 为单实例(非 per-account可持有 mutable 状态用于
资源管理(与适配器的 INV-5 无 mutable 状态约束不同)。
- httpx 连接池在 ``onInit`` 创建并注入 ``ILinkClient````onUnload`` 解除
引用后关闭;连接数上限对齐 manifest.json 中
``resource_quota.max_connections=10``。
- 长轮询拉取由 ``StreamWorker`` 通过 ``PullerAdapter`` 统一管理,
``LifecycleHandler`` 不持有长轮询句柄。
- ``onReconfigure`` 校验不可热更新字段,变更时抛 ``ConfigRestartRequiredError``
校验失败保持原基线以支持宿主回滚。
- ``onFail`` 不抛异常、不静默吞错logger 失败时回退到 ``sys.stderr.write``
不阻断 FR-36 优雅降级流程。
依赖方向:仅 import ``yuxi.channels.contract.*`` + 标准库 + httpx
不污染框架层。
