perf(gate): 大幅优化启动速度与票卡事件响应

- 版本号从 v1.5.31 升级至 v1.5.32
- 启动参数优化：外设等待间隔 0.5s→0.2s、最大重试 40→20、握手重试 20→8、启动重绘时长 20s→3s
- handshakeMonitor：移除不必要的 clearOk 严格检查，满足 scale+size 即视为握手成功
- 移除启动阶段阻塞的两次同步 HTTP 请求（站名映射/远程版本），改由后台异步任务执行
- startupRedrawTask：简化为仅启动初重绘 3 次即进入长休眠，避免频繁重绘抢占主循环
- 票卡处理：扫描去重窗口 500ms→200ms、PASS 后回退休眠 0.35s→0.1s
- 后台版本检查：VERSION_CHECK_INTERVAL 5s→15s，降低网络占用
