AGC 支持 Anthropic 独立网关路由与后台协议选项

新增平台 Anthropic 网关路由 /api/llm/anthropic/{*path}，复用账号 Router 凭据边界
OpenAI 侧规范路径改为 /api/llm/v1/responses 与 /api/llm/v1/chat/completions，旧路径保留兼容
baseUrl 不再携带路由与版本段，统一由协议自己拼 v1/<op>
cc 执行器改走平台网关，ANTHROPIC_AUTH_TOKEN 复用平台会话，不再直连 Router
后台模型目录 agentMode 增加 anthropic，管理页与客户端契约同步
补齐三条路由埋点与静态段白名单，新增三条回归测试
同步后端架构文档、模型别名文档与排障记忆
