/**
 * Act on an operator-initiated update-available event.
 *
 * Logs receipt, then — if an npm auto-update service is available — invokes the
 * manual, gate-bypassing `triggerUpdate()` and logs the outcome. When no
 * service is wired (e.g. the daemon was started without one), logs a clear
 * warning instead. Never throws: errors from `triggerUpdate()` are caught and
 * logged so the WebSocket loop is not disrupted.
 *
 * @param event - The update-available event from the dispatcher.
 * @param npmAutoUpdateService - The agent's npm auto-update service, or null/
 *   undefined when none was provided to the daemon.
