Backend fix:
- Remove return_properties from hierarchical chunk query
- Weaviate returns nested objects (work, document) when return_properties is not specified
- This allows chunks to have work.author and work.title available
Frontend improvements:
- Truncate long section titles to 80 chars with ellipsis
- Hide section_path if identical to title (avoid duplication)
- Work and author badges should now display correctly in chunk metadata
