Fired when the user activates a gated reasoning-effort row whose resolved upsell presentation is 'Upgrade'. This activation bucket is derived from the item's upsell type and free-trial eligibility; the following native route is still determined by the item's upsell value, so this event can precede a subscription-upsell request. Despite the historical '_shown' suffix, this is an activation event, not an impression.
