Subject: [PATCH] fix(window): fix isEnabled() for Windows platform
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On Windows, DPlatformHandle doesn't support isEnabledDXcb which is
a Linux-specific function. Return handle existence directly instead
to ensure the window reports correctly as enabled on Windows.

fix(window): 修复 Windows 平台下 isEnabled() 的兼容性问题

DPlatformHandle::isEnabledDXcb 仅在 Linux 下可用，在 Windows
上直接返回 handle 是否存在以正确报告窗口启用状态。
