kline_py.rs 中 BSP_CACHE、KLINE_IDENTITY、BAR_IDENTITY 使用了 thread_local!。主线程调用 识别买卖点() → 买卖点信息.add() 写入的是主线程的 PySet，backtrader 策略线程读取的是自己线程独立的空 PySet。 修复：将三个缓存从 thread_local! 改为全局 static + std::sync::LazyLock<RwLock<HashMap<...>>> 影响分析 这些身份缓存的影响与 KLINE_IDENTITY/BAR_IDENTITY 不同——它们只影响 Python 对象身份（is 比较），不直接影响数据内容（因为 Rust 数据通过 Arc 共享，读写都是同一份）。 具体后果： - 不同线程访问同一个 Rust Arc 会得到不同的 Python wrapper 对象 - a is b 跨线程比较返回 False，哪怕它们包装同一个底层 Rust 对象 - 每个线程维护一份独立缓存，内存浪费（不过 wrapper 很小）
