/**
 * Hook: session end — the moment PAL updates itself.
 *
 * Every agent PAL targets fires one of these when a session is done: Claude's
 * SessionEnd, Cursor's sessionEnd, Codex's SessionEnd, Copilot's sessionEnd.
 * opencode has no session-end event and calls the same library function from its
 * plugin when the server is disposed.
 *
 * Closing is the right moment because the work is over: the reinstall cannot
 * rewrite the config of a session still in use, and opening PAL costs nothing.
