补全过滤入口与直接兑换，优化兑换分类和 WSS 建连

- GUI 接线 Exchange 绑定：新增「直接兑换」按钮，结果带 category/message 并进入结果面板
- 补 -max-price/-min-left（CLI 与 GUI 设置），Target 的价格与库存过滤不再悬空
- 删除死代码 sendUpdateUserInfo 及其请求结构体（浏览器流程不含该帧）
- ClassifyExchange 改为多路判定：合并 msg/actPreCondition/exchangeInfo 文案，status=200 且有 orderId 视为成功，新增 condition 分类（precondition 门禁）
- WSS 建连改为锁外 dial、锁内注册，同 uid 并发调用共享一次握手
- 默认传输层统一为 http（CLI/GUI/README），.gitignore 忽略 .DS_Store
- 同步 Wails 依赖升级（2.12.0 -> 2.15.0）并重新生成前端绑定
