Previously, `create_paired()` returned two full Transport objects, and
callers would immediately call `from_transport()` on the remote side to
extract its underlying fd. This wasted resources: the remote
Transport's IO thread, wakeup pipes, and send queue were initialized
only to be torn down without ever sending or receiving a message.
Now `create_paired()` returns `{Transport, TransportHandle}` — the
remote side is born as a lightweight handle containing just the raw fd,
skipping all unnecessary initialization.
Also replace `release_underlying_transport_for_transfer()` (which
returned a raw int fd) with `release_for_transfer()` (which returns a
TransportHandle directly), hiding the socket implementation detail
from callers including MessagePort.
