feat(input): lock cursor during fullscreen streaming

[qiin2333]

改了啥呀

• 接入 API 22+ 的 OH_WindowManager_LockCursor / OH_WindowManager_UnlockCursor，把会跑出全屏串流窗口的系统光标按住啦
• 普通桌面模式保留光标跟随并限制窗口边界；游戏鼠标模式固定本地光标，直接转发 ArkUI rawDelta
• 串流菜单、窗口失焦、退后台和串流结束时释放光标，恢复焦点或关闭菜单后重新锁定
• 通过运行时符号解析兼容 compatibleSdkVersion 12，并声明 LOCK_WINDOW_CURSOR 权限；旧系统和不支持设备继续使用原鼠标路径

为啥要改

全屏串流连接实体鼠标时，系统光标仍可能碰到窗口外或边缘区域，沉浸模式和应用层回弹管不到这一层。现在由窗口管理器负责边界，输入处理器只负责把位移送去远端，职责终于不打架了，杂鱼边缘状态退散。

本 PR 只处理 Issue 中第一项鼠标锁定需求；三指触控手势不在本次范围，因此不会自动关闭整个 Issue。

验证

• npm run check
• node hvigorw.js assembleApp --mode project -p product=default -p buildMode=debug --no-daemon
• API 24 模拟器绝对模式：followMovement=true，日志确认 mode=confined
• API 24 模拟器游戏鼠标模式：followMovement=false，日志确认 mode=locked 并进入 ArkUI rawDelta 路径
• Back 打开菜单会解锁，Back 关闭菜单会按原模式重新锁定
• Home 退后台由系统自动释放，回到前台重新锁定成功

模拟器缺少 INPUT_MONITORING 权限时会正确回退 ArkUI + DisplaySync。模拟器的视频解码仍为黑屏，且 UITest 注入的是触摸事件，实体鼠标 rawDelta 的手感仍建议在真机补充确认。

Summary by CodeRabbit

• 新功能

  • 支持全屏串流时锁定系统光标，提升鼠标相对移动体验。
  • 增加窗口焦点感知，窗口失焦或游戏菜单打开时自动暂停鼠标拦截，恢复后自动继续。
  • 游戏菜单关闭时统一恢复鼠标输入状态。

• 改进

  • 优化相对鼠标移动数据处理，提升移动响应的准确性。
  • 增加光标锁定能力检测及自动释放机制，避免窗口切换或退出后残留锁定状态。
  • 补充光标锁定所需的系统权限配置。
