- **Tests**:
- Introduced `database-operations.test.ts` to validate core database functionalities, including initialization, CRUD operations, statistics retrieval, and search capabilities.
- Added `dimension-standardization.test.ts` to ensure vector dimension consistency (fixed at 512) throughout operations like embedding, configuration, and validation.
- Enhanced test cases to include scenarios for adding, retrieving, and handling errors for incorrect vector dimensions.
- **Documentation**:
- Created `VECTOR_DIMENSION_STANDARDIZATION.md` to detail the transition to standardizing vectors to 512 dimensions, rationale for the change, potential impacts, and migration steps.
- Includes best practices for handling vectors and utilizing the built-in embedding functions.
**Purpose**: Improve system robustness with comprehensive test coverage focusing on critical database and vector operations while providing clear documentation for developers to adapt to the standardized vector dimensions.
