Copilot I think you don't need to change cmake/presets/CMakeWinConfigPresets.json which might change default behaviro. Only add support vs 2026 but still using 2022 by default

Reverted the CMakeWinConfigPresets.json change — VS 2022 remains the default. The only change now is adding "Visual Studio 18 2026" as a choice in build.py. See commit e2eb9f8.
