"""微信 iLink（ClawBot）渠道插件入口。

实现 ``CHANNEL_ENTRY`` 契约，注册 11 个适配器与生命周期钩子，返回
``PluginManifest``。由宿主在 loaded 阶段通过 ``importlib`` 导入并调用。

调用顺序（严格）：
1. ``declareAccessiblePorts`` / ``declareInjectablePipelines`` /
   ``declareResourceQuota`` 声明能力边界（必须在 ``getXxxPort`` 之前）。
2. ``getXxxPort`` 获取被驱动端口实例。
3. 实例化 ``WeChatILinkLifecycleHandler`` 与 ``ILinkClient``。
4. 实例化并注册 11 个适配器（puller / inbound / outbound / session /
   status / login / lifecycle / probeable / doctor / wizard / whitelist）。
5. ``registerLifecycleHandler`` 注册生命周期钩子（鸭子类型调用）。
6. 返回 ``PluginManifest``。

适配器 DI 说明：
- 8 个适配器（puller / inbound / outbound / login / lifecycle / probeable /
  doctor / wizard）接收 ``(client, logger_port)``。
- ``whitelist`` 适配器接收 ``(cache_port, logger_port)``：白名单数据本地
  存储于 CachePort，不调用渠道侧 API，无需 ILinkClient。
- ``session`` / ``status`` 适配器无状态（INV-5），无 ``__init__`` 参数，
  仅做协议转换，所有数据从 raw_event.payload 提取。

长轮询传输管理：iLink 通过 ``PullerAdapter`` 长轮询 ``getupdates`` 拉取
消息，``PullerWorker`` 由传输引擎通过 ``ChannelAccountOnline`` /
``ChannelAccountOffline`` 领域事件触发启停，``LifecycleAdapter`` 与
``LifecycleHandler`` 不自管理轮询任务。

依赖方向：仅 import ``yuxi.channels.contract.*`` + 标准库 + 同插件内部模块，
不污染框架层。
