+/**
+ * ════════════════════════════════════════════════════════════════
+ * 铸渊 MCP Server · guanghulab-mcp-server
+ * ════════════════════════════════════════════════════════════════
+ *
+ * 光湖代码仓库的 MCP (Model Context Protocol) 服务端。
+ * 让 WorkBuddy / CodeBuddy 等编程 AI 通过 MCP 协议直接操作仓库，
+ * 无需每次手动发送 Gitea 令牌。
+ *
+ * 核心设计：
+ *   - Gitea 令牌存在服务器端，AI 端只需一个 MCP 连接密钥
+ *   - 换号时只需重新连接 MCP，不用重新发令牌
+ *   - 所有操作通过 Gitea API 代理，安全受控
+ *
+ * 传输协议：Streamable HTTP (MCP 2025-03 规范)
+ *   - POST /mcp — 客户端→服务器请求
+ *   - GET  /mcp — SSE 通知流
+ *   - DELETE /mcp — 关闭会话
+ *
+ * 认证方式：Bearer Token (MCP 连接密钥)
+ *   - Header: Authorization: Bearer <MCP_ACCESS_KEY>
+ *   - 密钥在 /data/guanghulab/mcp-server/.access-key 中
+ *
+ * 部署位置：guanghulab.com CVM (广州)
+ * Nginx 代理：/mcp → 127.0.0.1:8083
+ *
+ * 签发：铸渊 · ICE-GL-ZY001
+ * 版权：国作登字-2026-A-00037559 · TCS-0002∞
