/**
 * @file SessionMenu — a session row's right-click menu (sidebar, the workspace
 * home's Recents, the archived fold), and a bare live tab's (`session` null —
 * the sidebar's **New session** row). Every item is something the row already
 * does: open it the way its click does (a live pane attaches, an ended session
 * opens its conversation — never a resume), open a live one in a split,
 * rename / pin / unpin / archive / unarchive when the list offers them, copy its id, open
 * its analysis page, and end its live tab as the tab's buttons do (`endRuns`,
 * after the same confirm for an AI tab, which may be mid-turn): **Sleep** stops
 * it and keeps the session listed to resume later, **Close tab** stops it and
 * archives the session.
