* fix: bound HDR and video extraction resources * fix: trim negative video extraction preroll * fix: skip invisible video extraction windows * fix: preserve negative-start loop and held tails * fix: cap finite video slots to source duration * fix: bound held-tail frame extraction * fix: plan from playable video duration * fix: preserve open-ended held video tails * fix: resolve held tails from decoded frames * fix: normalize final-frame probe timestamps * fix: handle unseekable final-frame sources * fix: dedupe final-frame probes per render * refactor: clarify output dynamic range contract
