Add TCPStreamer/TCPStreamerClient (TCP transport behind the UDPSServerI/UDPSClientI seam), an optional single in-process TCPStreamService serving many streams over worker threads, multiplexed SUBSCRIBE (comma list, stream index in fragmentIdx), and TCPStreamJoin, which merges several streams into one sample-and-hold stream paced by a master. StreamHub takes a comma list of streams over one connection. Includes GTests, E2E scenarios s58-s73 and docs. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
