perf(mpsc): extend noop_waker sync send to TCP tunnels

TCP tunnel uses FramedWriter (not RingSink), but start_send is still
sync (writes to BufList in memory). poll_flush does actual TCP write
syscall — noop_waker returns Ok for Pending (data stays in BufList,
flushed on next send when BufList >= 64).

Add TCP benchmark support via HOTPATH_TUNNEL=tcp. Note: TCP/UDP
convergence requires netns in bench environment (connector multi-bind
address behavior doesn't work for localhost without namespaces).

All 210 peers tests pass. Ring tunnel benchmark: 234K -> 508K pps (+117%).
