/**
 * Vector DB export — convert crawled screens to embedding-ready chunks.
 *
 * Produces a JSONL file where each line is one chunk ready for upsert into
 * Pinecone, Qdrant, Weaviate, or any vector store. The embedding itself is
 * NOT generated here (requires an embedding model at the user's end) — we
 * produce the text chunks + metadata, and the caller embeds them.
 *
 * Format per line (JSONL):
 * {
 *   "id": "<screenId>-<chunkIndex>",
 *   "text": "<chunk text>",
 *   "metadata": {
 *     "screenId": "...",
 *     "projectId": "...",
 *     "tenantId": "...",
 *     "url": "...",
 *     "screenName": "...",
 *     "chunkIndex": 0,
 *     "totalChunks": 3,
 *     "crawledAt": "2026-...",
 *     "wordCount": 142
 *   }
 * }
