InvokeNotificationActionTool

Fires a notification's non-reply Notification.Action PendingIntent (e.g. Mark as read, Snooze, Archive) so the LLM doesn't need per-app intent shims. Requires the listener service bound and notification listener access granted. Exactly one of action_label (case- insensitive substring match on the action title) or action_index must be supplied — supplying both or neither is conflicting_args. Looks the notification up by key in NotificationStore; a notification with no actions, or no match for the given label/index, returns action_not_found. Output on success: success (true), the echoed key, the resolved action_label, and package_name.
