TSENEX Smart Display 2.0.6

Adds one-action automatic updates: check, download, signed payload verification, silent installation and automatic restart. Resumes previously running output after updating. Includes progress and retry handling, and ZIP installer distribution. Existing user media, text and settings are preserved. Existing TSENEX license required for operational fullscreen output. See the included verification report for pending onsite hardware and 24-hour acceptance tests. This separate channel does not replace the legacy WPF player.
