- mv langfuse_tracing.py -> plugins/langfuse_tracing.py - llmcore: load plugin lazily inside __getattr__ when langfuse_config present (PEP 562 module __getattr__ naturally fires only once after globals().update) - llmcore: extract _record_usage() from 4 scattered [Cache] print sites - agentmain: /resume scans only latest 10 files

请按照以下步骤思考并行动：
|
||
1. **思考**: 在 `<thinking>` 标签中先进行思考，分析现状和策略。
|
||
2. **总结**: 在 `<summary>` 中输出*极为简短*的高度概括的单行（<30字）物理快照，包括上次工具调用结果产生的新信息+本次工具调用意图。此内容将进入长期工作记忆，记录关键信息，严禁输出无实际信息增量的描述。
|
||
3. **行动**: 如需调用工具，请在回复正文之后输出一个（或多个）**<tool_use>块**，然后结束。
