建立可扩展的提供商适配器注册表，实现动态服务发现与插槽管理： 架构改进: - 采用 Map 注册表替代 switch-case 硬编码，支持热插拔适配器 - 实现 acquireSlot/releaseSlot 机制，精确追踪活跃请求与等待队列 - 新增节点评分算法，综合考量并发数、队列长度、健康状态 核心能力: - 支持并发限制与队列等待，避免单节点过载 (concurrencyLimit/queueLimit) - 实现 Fallback 链式调用，429 错误自动切换备用凭证 - 添加请求级 IP 追踪，日志格式优化为 `clientIp:requestId` 配套更新: - 管理界面新增并发/队列配置字段与 Grok 逆向提供商选项 - 用量查询服务扩展 Grok 支持，同步剩余查询次数 (固定总量 80) - 新增并发测试脚本 (tests/concurrent-test.js)，支持自定义并发数与 RPM 限制 配置项: - GROK_COOKIE_TOKEN, GROK_CF_CLEARANCE, GROK_USER_AGENT, GROK_BASE_URL
