milescovielloandClaude Opus 5.5 2f196610dd feat(libkernel): pass descriptors in SCM_RIGHTS messages on Unix sockets ...

sendmsg on a guest Unix-domain socket now takes FreeBSD SCM_RIGHTS control
messages (SOL_SOCKET level, data at offset 16) and sends their descriptors
with the host's SCM_RIGHTS; recvmsg receives them, installs received sockets
as guest sockets and writes FreeBSD's control record back, truncated to the
caller's buffer with MSG_CTRUNC. A closed descriptor returns EBADF, another
level or an overlong record EINVAL. Windows, other control types, IP
sockets and MSG_PEEK with a control buffer still throw.
