根因: Experience 结构体没有 tool_used 字段，PatternAggregator 从
context 字段提取工具名（语义混淆），导致工具信息不准确。

修复:
- experience_store.rs: Experience 添加 tool_used: Option<String> 字段
  (#[serde(default)] 兼容旧数据)，Experience::new() 初始化为 None
- experience_extractor.rs: persist_experiences() 从 ExperienceCandidate
  的 tools_used[0] 填充 tool_used，同时填充 industry_context
- pattern_aggregator.rs: 改用 tool_used 字段提取工具名，不再误用 context
- store_experience() 将 tool_used 加入 keywords 提升搜索命中率
