The Windows NSIS step failed under wine for two reasons: no X display (nodrv_CreateWindow) and missing 32-bit libraries (failed to load syswow64\ntdll.dll). The job now installs xvfb + wine32:i386 and runs the desktop build under xvfb-run, with Gecko/Mono lookups disabled. Also add `images` and `desktop` dispatch inputs so either half of the CD can be skipped (e.g. desktop-only or images-only releases).
