dsh-keep-going: Resuming Interrupted Sessions After a DSH Restart

`dsh-keep-going` is a DeepSeek Harness (DSH) plugin designed to address conversation interruptions caused by gateway restarts. It leverages persistent session history to automatically resume unfinished goals after a restart, does not process completed or archived tasks, and preserves states awaiting user responses. The plugin is distributed exclusively via GitHub, provides commands for restarts, status checks, and tombstone clearing, and must be activated by restarting the DSH process with a service manager.
