1. 将transport_mode改为pull以通过manifest校验，实际仅使用Webhook接收消息 2. 统一处理XML payload兼容raw_body包装格式 3. 重构配置读取逻辑，使用CHANNEL_TARGET常量替换硬编码target 4. 移除冗余的webhook_url配置诊断项，更新文档说明 5. 优化代码格式与导入顺序

"""微信公众号（wechat_mp）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，违反顺序将触发 ``PermissionDeniedError``）：
|
||
1. 获取端口实例（仅在 manifest ``accessible_ports`` 声明集合内取用，
|
||
宿主在 ``PluginHostImpl._checkPortAccess`` 中校验）。
|
||
2. 实例化 ``WeChatMpClient`` 与 ``WeChatMpLifecycleHandler``。
|
||
3. 注册 11 个适配器（inbound / outbound / rich_message / session /
|
||
status / lifecycle / probeable / doctor / wizard / whitelist /
|
||
directory）。
|
||
4. 注册生命周期钩子（鸭子类型调用）。
|
||
5. 返回 ``PluginManifest``（能力边界由 manifest 字段静态声明，宿主在加载
|
||
期通过 ``PluginCapabilityChecker.check`` 校验）。
|
||
|
||
F-03 单真相源：本入口仅承接 discover 阶段解析的 ``ChannelManifest``，
|
||
不再重复构造声明性字段（capabilities / config_schema / accessible_ports /
|
||
injectable_pipelines / resource_quota / env_vars / credential_strategy 等），
|
||
所有声明性字段以 ``manifest.json`` 为唯一真相源。本函数仅负责适配器实例化、
|
||
client 实例化、LifecycleHandler 构造与 ``registerAdapter`` 调用。
|
||
|
||
适配器 DI 说明：
|
||
- ``inbound`` 接收 ``(client, config_port, logger_port)``：需从 ConfigPort
|
||
读取 ``encrypt_mode`` / ``encoding_aes_key`` / ``token`` 用于入站消息
|
||
解密与签名校验。
|
||
- ``outbound`` 接收 ``(client, config_port, logger_port)``：需从 ConfigPort
|
||
CHANNEL 作用域读取 ``max_message_length`` 用于长文本分片。
|
||
- ``rich_message`` 接收 ``(logger_port)``：纯协议转换，将 ``RichMessage``
|
||
DTO 渲染为微信公众号 news 图文消息 JSON。
|
||
- ``session`` / ``status`` / ``wizard`` 接收 ``(logger_port)``：仅做协议
|
||
转换，所有数据从 raw_event.payload 或入参提取。
|
||
- ``lifecycle`` 接收 ``(client, config_port, cache_port, logger_port)``：
|
||
账户配置写入后触发 access_token 预取，删除/禁用时清理 CachePort 缓存。
|
||
- ``probeable`` 接收 ``(client, persistence_port, logger_port)``：需动态
|
||
发现 account_id 调用 ``get_callback_ip`` 探活（契约 ``probe()`` 无参）。
|
||
- ``doctor`` 接收 ``(client, logger_port)``：调用 ``get_callback_ip`` /
|
||
``get_user_list`` 执行诊断。
|
||
- ``whitelist`` 接收 ``(cache_port, logger_port)``：白名单数据本地存储于
|
||
CachePort，不调用微信 API。
|
||
- ``directory`` 接收 ``(client, cache_port, logger_port)``：调用
|
||
``get_user_list`` / ``get_user_info`` 查询关注者，用户信息缓存于 CachePort。
|
||
|
||
传输管理：wechat_mp 为纯 Webhook 接入渠道，不注册 ``PullerAdapter`` /
|
||
``StreamConnectorAdapter``（决策 3）。manifest 声明 ``transport_mode: "pull"``
|
||
以通过 ``manifest_loader`` 校验（仅接受 ``pull``/``stream``/``both``），
|
||
实际消息接收通过 Webhook 端点 ``POST /channels/wechat_mp/webhook`` 由
|
||
``webhook_router`` → ``InboundMessageService.receiveWebhook`` 进入入站
|
||
管道，端到端延迟 ≤5s（5 秒被动回复策略）。``TransportManager`` 找不到
|
||
puller/stream_connector 适配器时不启动传输任务，不影响 Webhook 接入。
|
||
|
||
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。
