fix: macOS PlayTools/SCK 几处小修正 (#16276)

fix: macOS 相关几处小修正

- PlayToolsController: screencap_rgba/screencap_bgr/toucher_commit 调用
  open() 时未检查返回值，连接失败时继续操作会写坏的 socket
- PlayToolsController: start_game() 日志写成了 InputText，应该是 StartGame
- OcrPack: macOS 分支日志里残留了多余的 "rec" 字样
- MacSCKHelper: 析构时 stopCapture 是异步的，没等回调完成就释放了
  stream/output/queue，可能踩到野指针；改用信号量等停完再释放
