/**
 * video-factory — GPU infrastructure control for Pi.
 *
 * One package: the agent can provision, deploy, run, monitor, and destroy GPU
 * workloads on whatever cloud provider you have access to (RunPod, Vast.ai,
 * Modal, Lambda, Prime), with video generation as the first-class workload
 * (H3, Wan 2.2, HunyuanVideo, Seedance).
 *
 * Security: this extension executes provider CLIs and can spend real money.
 * The spend policy (.pi/gpu/policy.json) is the trust boundary — provisioning
 * above the confirm threshold always asks the user. Review before installing.
