/**
 * @file stopSession — the one way the UI ends live panes: **Stop** kills the
 * pane and ARCHIVES the session it held (`DELETE /api/run/:id?archive=1`), so
 * a session the user closed leaves its workspace's lists; **Sleep** kills the
 * pane and KEEPS the session listed, to be resumed later by sending it a
 * message. Both ask first when any pane holds an AI agent (it may be
 * mid-turn); a plain shell holds no session, so it neither asks nor sleeps.
 * Used by the tab bar (`ConsoleTabs`), the split panes (`Workspace`) and a
 * session's right-click menu (`SessionMenu`).
