Strict JSON parsers (including the one used by cmake 4.x) reject trailing commas with Missing '}' or object member name and refuse to read CMakePresets.json at all, which breaks every preset — not just the MSVC one containing the comma.
One-character fix; Windows-only config, but the JSON parse failure is cross-platform. No functional change.
