shuiqian520/dsh-session-delete

Permanently deletes one session from the sidebar session menu, or several at once from the "..." menu beside the sidebar section title: tick sessions in the list (running ones are refused), then confirm in a dialog — log directory, workspace membership, live Host instances and the client list row are all cleaned. The same "..." menu also collects the session search and view options. It also sweeps rows whose log is already gone, and retries a user message or an assistant reply from the button right of Copy.
