../data/raw relative to WORKDIR /app resolves to /data/raw which is
outside the volume mount (./data:/app/data). The scraper wrote 583
pages to the ephemeral container filesystem and they were lost on exit.
Changed to /app/data/raw in both scraper and indexer so the JSONL file
lands inside the mounted volume and persists between containers.
