摘要: Windows 环境启动插件时，在初始化消息收集器链路中导入监控模块失败，prometheus_client 依赖的 wsgiref.simple_server 无法导入，导致自学习服务编排失败；同时提到存在 gbk codec can't encode 的编码问题。

相关模块: monitoring, core factory / service orchestration, message capture

相关文件: services/monitoring/metrics.py, services/monitoring/__init__.py, services/core_learning/v2_learning_integration.py, core/factory.py, core/plugin_lifecycle.py, main.py

可能原因: 插件在初始化时会导入 services/monitoring/metrics.py（经由 services/core_learning/v2_learning_integration.py -> services/monitoring/init.py），该文件直接 import prometheus_client；而 prometheus_client/exposition.py 在导入阶段会执行 from wsgiref.simple_server import ...。在用户的 AstrBot 打包/裁剪运行环境（Windows，.astrbot\data\site-packages）中，标准库 wsgiref 可能被移除/不完整，或被同名第三方包/路径污染导致 stdlib wsgiref 未被正确解析，从而触发 ModuleNotFoundError。该异常在 core/factory.py:create_message_collector 捕获后包装为 ServiceError，导致核心模块 MessageCollectorService 创建失败。

建议方案: 在插件侧避免在导入阶段强依赖 prometheus_client/wsgiref：

1. 修改 services/monitoring/metrics.py：将 from prometheus_client import ... 移入实际需要启用 metrics 的初始化函数中，并用 try/except 捕获 ModuleNotFoundError；缺失时降级为 No-Op 指标实现（Counter/Gauge/Histogram/CollectorRegistry 提供空壳类或直接跳过注册）。
2. 修改 services/monitoring/init.py：不要在模块 import 时无条件导出 metrics 相关对象；改为惰性加载，或根据配置开关（如 WebUI/monitoring enable）决定是否导入。
3. 修改 core/factory.py:create_message_collector：当监控模块初始化失败时，不应阻断 MessageCollectorService 创建；记录 warning 并禁用 metrics 子系统（让消息采集/学习主流程继续工作）。
4. 针对 gbk codec can't encode：在 main.py / core/plugin_lifecycle.py 的日志输出处避免直接输出可能含有非 GBK 字符的文本，或对日志 handler 设置 UTF-8（此项需结合实际报错堆栈补充定位）。
