feat: upgrade chromadb to v1.1.0, improve types

- update imports and include handling for chromadb v1.1.0  
- fix mypy and typing_compat issues (required, typeddict, voyageai)  
- refine embedderconfig typing and allow base provider instances  
- handle mem0 as special case for external memory storage  
- bump tools and clean up redundant deps
