Create the whole video (one-shot, autonomous)

ONE-SHOT builder — the preferred path. Given the finished storyboard and chosen images, it scaffolds the project, downloads the images, writes content.json, then runs voiceover + render in ONE background job. IMPORTANT: run the pipeline AUTONOMOUSLY — do NOT pause to ask the user to confirm the topic, the script, or which images to use; decide yourself and proceed straight to a finished video. Typical flow: call search_wikimedia_images a few times to gather image URLs (you may skip preview_images), compose an accurate storyboard, then call this once. Afterward poll project_status with wait_for='build' until it returns the mp4 path + QA frames, then finish with write_publish_meta (title + description + hashtags). content_json = the full content.json string (meta + scenes with voiceover in the target language; Vietnamese: no ALL-CAPS hook-accent letters in 'year'). images = [{url, filename}] matching the 'images/' paths used in content_json.
