Couchside agent 2.9.133

• Couch Mode now explains when automatic TV input switching is unavailable, without implying that a paired TV has no working controls. TV power, session switching, display and audio behavior are unchanged.
• Includes 2.9.132 secure-connection responsiveness and private, atomic file uploads, plus the earlier transfer-ticket permission and controller-diagnostic improvements.
• This is an agent update; no phone app update is required for the clearer stage explanation.
