- clamp LLM-derived page indices in _get_text_of_pages and
get_text_of_pdf_pages_with_labels; dedupe get_text_of_pdf_pages
- guard _normalize_tree and folders/documents iterations against
explicit nulls in cloud API responses
- coerce cloud OCR page numbers to int before filtering in
get_page_content
- folder cache: raise on missing folder id instead of caching None;
stop caching name-not-found so later lookups can succeed
- defang doc_id in agent doc-context prompt
- append api-key hint to 401 errors (request, legacy and streaming
paths)
- remove stale legacy JSON workspace sample data unreadable by the
SQLite storage
* Consolidate tests/ into examples/documents/
* Add line_count and reorder structure keys
