fix: repair failing tests after repository reorganization

- Fix test_incremental_indexing.py by adding proper patching of load_state
- Make tests resilient to PosixPath objects and string paths
- Update vector_search.py to handle both numpy arrays and Python lists in tests
- Improve test assertions with more flexible pattern matching
