On Windows every socket error was OtherError. Each Winsock code now gets what errnoToIOError gives the errno of the same name, so a reset is ResourceVanished as on POSIX. WSAEINTR stays OtherError: it is what closesocket gives a blocked call, not an interrupt. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Ports #632 from v3.2 to master: on Windows, a Winsock error gets the
IOErrorTypeof the errno of the same name, rather thanOtherError.The cherry-pick conflicted only in the test's imports. On master the Windows
import GHC.IO.Exception (IOErrorType(..))inNetwork/Socket/Internal.hswas then unused, so the second commit drops it.Tested on Windows 11 with GHC 9.12.4.20260713 under WinIO and with No IO Manager, and with GHC 9.8.2: 115 examples, 0 failures each, and no compiler warnings beyond those master already has. macOS: 119 examples, 0 failures.
