/**
 * gen-video handler — POST ab-api /model/genVideo, then poll /model/getVideoStatus.
 *
 * Thin forwarder: the model roster, friendly aliases, defaults and per-model
 * constraints (aspect ratios / resolutions / durations / reference-image caps)
 * come from ab-api's capabilities catalog (see capabilities.ts), not from this
 * package. Pre-flight validation here is purely data-driven from that catalog —
 * the CLI carries no model matrix — and ab-api re-validates authoritatively.
 *
 * --model accepts a friendly alias or a full id; ab-api also resolves aliases
 * server-side, so an unknown value still passes through to the backend.
 *
 * Local image paths for first/last/reference frames are read and base64-encoded
 * into a data: URI; https / data: URIs pass through unchanged. Reference videos
 * and audio are the exception — they must already be public URLs, see
 * `requirePublicUrls`.
