refactor: ce-simplify-code 审查修复 — 去重 + 效率 + 死代码清理
...
3 个审查代理（复用/质量/效率）发现 15 个问题，全部修复：
效率与安全（6 项）：
- MCPClient 缓存 MultiServerMCPClient 单例 + aclose()，修复连接/子进程泄漏
- _rate_limits 清理空 IP 条目，修复 X-Forwarded-For 欺骗下内存泄漏
- _seen_nonces 改用 OrderedDict，O(1) 摊销过期清理
- webhook 后台任务加 Semaphore(20) + 任务引用追踪，限制无界并发
- _build_adapter 用 asyncio.gather 并行解密 secrets
- 适配器实例缓存（_adapter_cache），token TTL 缓存跨请求命中
去重（4 项）：
- header_get 提取到 channels/base.py，4 个适配器统一 import
- _get_client/close() 移入 MessageAdapter 基类，子类继承
- URLVerificationChallenge 统一到 base.py，feishu/slack/wecom 共用
- Transport ABC 添加 endpoint_url 属性，from_transport 不再访问私有字段
死代码与类型安全（5 项）：
- detect_cache_hit 死方法替换为 record_cache_result 公开 API
- execution_mode.value == "direct_chat" 改用枚举比较
- 删除 yielded_any 死变量、重复 from fastapi import Request、
多余 getattr 防御
