Kris 7174500a9a feat(wechat-mp): 新增微信公众号渠道插件完整实现
实现了微信公众号全功能渠道插件,包含会话解析、消息收发、富消息适配、生命周期管理、主动探测等核心能力,遵循单真相源设计原则,所有配置与常量统一从manifest.json与_constants.py获取。

"""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 通过 ``TransportManager`` 的 ``both`` 模式管理消息
接收manifest ``transport_mode: "both"``
- ``WebhookWorker``(优先):接收微信服务器 Webhook 推送(消息/事件),
端到端延迟 ≤5s5 秒被动回复策略)
- ``PullerWorker``降级Webhook 不可用时降级为无轮询(公众号无拉取
API此模式实际不可用仅保留契约一致性
两者由传输引擎通过 ``ChannelAccountOnline`` / ``ChannelAccountOffline``
领域事件触发启停,``LifecycleAdapter`` 与 ``LifecycleHandler`` 不自管理
传输任务(决策 3
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。
