📄 Description

This PR adds support for AF_UNIX (Unix domain sockets) on Windows using native Winsock functionality available in Windows 10 (1803+) and newer.

(Tom informed me about the availability of AF_UNIX on Windows, and here we are.)

Notes

AF_UNIX is enabled only when available at compile time (#ifdef AF_UNIX)
Uses <afunix.h> on Windows for sockaddr_un
Linux-only features (abstract sockets, peer credentials) are explicitly rejected on other platforms
Exposes AF_UNIX methods of Socket to all platforms but ensures graceful failure on unsupported systems.

Limitations on Windows

Path-based UNIX sockets only
No abstract socket namespace
No peer PID / credential support

Other

Examples and autotest are updated.
POSIX behavior is unchanged.

Please check.
