Subject: [PATCH] Plumb path_mtu_lookup into Windows run_tun_reader

The B3 path_mtu_lookup plumbing landed without updating the
windows_tun::run_tun_reader signature or its inner handle_tun_packet
call, breaking the Windows build. Linux/macOS variants and
TunWriter (Windows) were already plumbed; this brings the Windows
reader into line.

No behavioral change on any platform.
