fix(ci): Update Windows release build to use x64 platform

The solution file only has x64 configurations (Release-Full|x64,
Debug-Full|x64). The workflow was incorrectly trying to build with
Win32 platform which doesn't exist.

Changes:
- Platform=Win32 → Platform=x64
- Output path ./Release-Full/ → ./x64/Release-Full/
