/**
 * AgentMessage — 统一消息信封
 *
 * 核心抽象: Agent 永远不需要知道消息来自哪个渠道。
 * Transport 适配器负责将渠道特定格式转换为 AgentMessage,
 * Agent 只处理 AgentMessage, 通过 replyFn 返回结果。
 *
 * 这是将"飞书聊天"和"前端聊天"统一为同一概念的关键:
 *   - HTTP/SSE (Dashboard)  → AgentMessage { channel: 'http', ... }
 *   - WebSocket (Lark/飞书)  → AgentMessage { channel: 'lark', ... }
 *   - CLI (终端)             → AgentMessage { channel: 'cli',  ... }
 *   - MCP (IDE 扩展)         → AgentMessage { channel: 'mcp',  ... }
 *
 * @module AgentMessage
