- Add qt6-qttools-static (Qt6::UiTools)
- Add -fpermissive to CXXFLAGS for GCC 15 compatibility
- Disable CTK_USE_QTTESTING (requires XmlPatterns, removed in Qt6)
- Disable CTK_WRAP_PYTHONQT_LIGHT explicitly
- Remove python subpackage (PythonQt not rebuilt for Qt6 yet)

- Add qt6-qtshadertools-devel for VTK transitive deps

* Fri Mar 06 2026 Morgan Hough <morgan.hough@gmail.com> - 2026.01.26-0.2.20260126gitfd37b874
- Switch to Qt6 (COPR VTK 9.5 is Qt6-based, cannot mix with Qt5)

* Thu Mar 05 2026 Morgan Hough <morgan.hough@gmail.com> - 2026.01.26-0.1.20260126gitfd37b874
