Subject: [PATCH] fix: use QImage::flipped() for Qt6 compatibility
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace QImage::mirrored() with QImage::flipped() when Qt version >= 6.0.0
to ensure compatibility with Qt6 API changes.

fix: 适配 Qt6 图像翻转 API

在 Qt6 中 QImage::mirrored() 已被 QImage::flipped() 替代，
添加版本检查以确保 Qt5 和 Qt6 的兼容性。
