ConnectedPeerSocket and PeerRecvDrain are node/peer-side logic: the Transport trait never touches them, ActivePeer stores them, and node's encrypt worker drives them. They only happened to live under transport/udp. Relocate the handle types to a new src/peer/connected_udp/ module (socket.rs + drain.rs), which the node handler and encrypt worker reach via node -> peer (no new edge; a node home would have forced a peer -> node cycle). The udp transport keeps only the kernel-construction seam: open_connected_fd, now folded into udp/io.rs (the byte-layer home) behind a linux/macos-gated submodule and re-exported as transport::udp::open_connected_fd. The node handler builds the fd through it and adopts it via ConnectedPeerSocket::from_fd. Behavior-neutral: no wire/config/metric/log change; the per-packet hot path (bare-RawFd send_batch_gso/raw) is untouched. Preserves the Arc multi-owner contract, the drop-drain-before-socket ordering, and the drain's detach-on-Drop deadlock avoidance. Reconciles the old cfg(unix)/any(linux,macos) double-gate onto the single any(linux,macos) predicate.
