HyperFrames adds templated Lambda batch renders

This pushes HyperFrames past “HTML to video” and into serious batch-render infrastructure for personalized video at scale. The interesting part is not just the Lambda support, but the fact that the template model makes the whole pipeline repeatable and agent-friendly.

• –`data-composition-variables` turns a composition into a reusable render contract instead of a one-off scene
• –`lambda render-batch` is the real unlock: one input file, many personalized outputs, parallelized in one shot
• –The AWS stack is opinionated but practical: Lambda for compute, Step Functions for orchestration, S3 for artifacts
• –This is a better fit for marketing, onboarding, and campaign video than generic “AI video generator” tooling
• –It also makes HyperFrames feel more like infra for video automation than a standalone editor
