Module lance_client 

LanceDB vector database client

NOTE: This file is ~1232 lines (737 implementation + 495 tests). It exceeds the 600-line guideline but is kept as a single coherent unit because:

• Tests require access to private methods (must be in same file)
• The implementation represents a single logical component (LanceDB client)
• Splitting would compromise test coverage and code organization

Future refactoring could extract search logic into traits if needed.
