/**
 * Runware HTTP REST API client for video generation
 * Uses the REST API instead of the WebSocket SDK
 * API documentation: https://runware.ai/docs/en/video-inference/api-reference
 *
 * Video generation uses async delivery with polling:
 * 1. Submit task with deliveryMethod: "async"
 * 2. Receive taskUUID in response
 * 3. Poll with getResponse until status is "success" or "failed"
