    python scripts/ingest_docs.py --input data/source_docs --config config/config.yaml

Reads every .pdf/.docx in --input and writes one markdown file per document into data.raw_dir, so
scripts/prepare_data.py can chunk + index it. We deliberately preserve:
  - headings  -> citation anchors (e.g. mypolicy#emergency-medical)
  - tables    -> markdown tables, because benefit/coverage LIMITS in travel insurance live in
                 tables and would otherwise be flattened into unreadable text.

PDFs: text + tables via pdfplumber, sectioned by page. Word: heading styles -> md headings,
paragraphs + tables preserved via python-docx.
