HeyGen Video Agent can revise selected scenes without rewriting the whole video

HeyGen's September API changelog adds scene-scoped Video Agent edits. A builder names the scenes and gives each a natural-language instruction; untouched scenes retain their script and visuals. Version checks reject stale edits instead of silently overwriting another change. Current documentation supports the workflow, but the exact day within September is not published.
