Companion beams now finish their fade after a killing hit

In Shattered Rift, companion beams now survive a killing hit and complete their original fade, following the live muzzle while keeping the endpoint on the killed target. Previously, a newborn beam could be removed before it was ever drawn. Damage, cadence and randomness were unchanged in the regression check, and harvesting keeps its original behavior. The short player-camera clip comes from a controlled encounter, not ordinary campaign play, and is not proof of hardware frame rate. Gun-mouth pixels, impact art, incoming damage and wider AAA work remain open.
