fix(core): handle chromadb import error gracefully (#192)

- Changed CHROMADB_AVAILABLE flag to _CHROMADB_IMPORT_ERROR exception storage
- Updated version from 0.3.1.7 to 0.3.1.8
- Modified import error handling to preserve original exception details
- Removed hardcoded ImportError message in favor of dynamic exception raising
- Added proper logger initialization using get_logger utility
