Summary

QQBot 收到消息时，系统会输出警告：
[context-engine] Context engine "lossless-claw" is not registered; falling back to default engine "legacy".
但实际情况是：
plugins.slots.contextEngine: "lossless-claw" 已在配置中设置
lossless-claw 插件已 loaded 且 enabled（openclaw plugins list 显示 status=loaded, enabled=true）
插件源正确指向全局 extensions 目录
警告仅在 前台控制台实时日志 中出现，不在文件日志中。

Steps to reproduce

安装 lossless-claw 到全局 extensions 目录
配置 plugins.slots.contextEngine: "lossless-claw"
通过 QQBot 发送一条消息
在前台控制台观察到此警告

Expected behavior

lossless-claw context engine 应被正确注册和使用，不应回退到 "legacy" engine。

Actual behavior

产生告警不生效[context-engine] Context engine "lossless-claw" is not registered; falling back to default engine "legacy".
