"""飞书渠道插件入口。

实现 ``CHANNEL_ENTRY`` 契约，注册 18 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. ``getXxxPort`` 获取被驱动端口实例（宿主已从 manifest.accessible_ports
   加载权限，无需运行时 declareXxx）。
2. 实例化 ``FeishuLifecycleHandler`` 与 ``FeishuClient``。
3. 实例化并注册 18 个适配器（17 个列表追加 + 1 个 identity_resolver 单实例）。
4. ``registerLifecycleHandler`` 注册生命周期钩子（鸭子类型调用）。
5. 返回 ``PluginManifest``。

per-account 适配器处理：``DirectoryAdapter`` / ``WhitelistAdapter`` /
``WizardAdapter`` 的 ``__init__`` 需 ``account_id``，但 ``CHANNEL_ENTRY``
在插件加载时不知具体账户，传入空字符串占位（``_PLACEHOLDER_ACCOUNT_ID``）。
实际 account_id 由 ``LifecycleAdapter.afterAccountConfigWritten`` 在账户配置
写入后按账户重建对应适配器，或由调用方通过 ``ConfigPort`` 动态读取。

WebSocket 长连接管理：飞书 WS 连接由 ``StreamWorker`` 通过
``FeishuStreamConnectorAdapter`` 统一管理（账号启用/禁用由
``ChannelAccountOnline``/``ChannelAccountOffline`` 领域事件触发），
``LifecycleAdapter`` 与 ``LifecycleHandler`` 不再自管理 WS 连接。

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。
