EU Official Journal PDFs (AI Act, CRA, NIS2, DSGVO, etc.) use
multi-column layouts that pypdf breaks into fragmented words
("Ar tik el" instead of "Artikel"). pdfplumber handles these correctly.
Backend priority: unstructured > pdfplumber > pypdf (auto mode).
Also increases D5 re-ingestion timeout to 3600s for large PDFs.
58 embedding-service tests passing. pdfplumber: MIT license.
