Build the netsnmp C extension on Windows using the MSYS2 mingw-w64 toolchain, which provides net-snmp (with net-snmp-config), gcc and a matching Python so setup.py works unchanged.

net-snmp is not packaged for Windows in MSYS2, vcpkg or conda-forge, so build the client library from source into the mingw64 prefix. This puts net-snmp-config on PATH so setup.py works unchanged. Result is cached. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014KG1c9XtKawkvig5PnZjC8
- setup.py: invoke net-snmp-config via sh on Windows (cmd.exe cannot exec the shell script) and link ws2_32 for the winsock symbols. - client_intf.c: use winsock2.h/ws2tcpip.h instead of arpa/inet.h and netdb.h on _WIN32.

setup-msys2 installs to $RUNNER_TEMP\msys64, not C:\msys64, so the cache never matched and net-snmp was rebuilt every run. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014KG1c9XtKawkvig5PnZjC8
