Why:
- Need to list documents to get document IDs for queries
- ProcessRequest should default to all 5 strategies
- paragraph_count should be optional (not always stored)
Changes:
- Added GET /documents endpoint with pagination
- Added DocumentListResponse model
- ProcessRequest now defaults to all 5 strategies
- DocumentResponse.paragraph_count now defaults to 0
Why:
- Need to parse .docx/.doc files into DocumentTree + markdown
- Need API endpoints for document upload, processing, and deletion
Changes:
- Parser: .doc→.docx conversion via LibreOffice, XML-level extraction for table-heavy docs, heuristic heading detection
- Service: upload, process (delegates to chunking), delete orchestration
- Routes: POST /documents, POST /documents/{id}/process, DELETE /documents/{id}, GET /strategies
