skipBreak

Cut the in-progress break short NOW (viewer skip). The renderer must end the break through its normal cut path so the sequencer still emits the balanced adend + adbreakend steps — exactly like the break-cut timer. No-op when no break is playing. The orchestrator (OptiViewAds.skipAd) owns the skip POLICY (controls.skipOffset gating); the renderer only performs the cut. Default no-op so renderers/fakes without a skip surface need not override.
