    - Remove unnecessary website_indexer.py file - Update test imports to use direct module imports - Update FastAPI version from 0.116.2 to 0.120.1 to match app branch - Regenerate poetry.lock file
When large sections are split and some chunks filtered due to being below min_chunk_size, part_number values were non-sequential and total_parts was incorrect.
