add HTML‑aware text splitter, raise batch size and large‑doc threshold, enhance progress spinner and error logging, rename ingestSpec to buildSpecDocuments and introduce hierarchical section processing.
- Move full‑section Document creation into an `else` block so it only occurs when no sub‑documents were created.
- Remove premature return that skipped adding the full section.
- Add post‑processing loop to log a warning for any final document exceeding `LARGE_DOC_THRESHOLD`.
