Struct MessageService 

pub struct MessageService {
    pub config: Config,
}

Message service

Provides core message functionality including creating, sending, and retrieving messages. Supports multiple message types: text, post, image, file, audio, media, sticker, interactive, share_chat, share_user.

Service 抽象接入：通过 impl_full_service! 为该服务实现 Service/ServiceObservability/ServiceBuilder/ServiceHealthCheck/ConfigurableService 等核心能力，统一服务行为与可观测性。
