- Add logging configuration to BrainyData for better control over verbose output.

- Refactor embedding functions to support customizable verbosity through new helper methods (`getDefaultEmbeddingFunction`, `getDefaultBatchEmbeddingFunction`).
- Ensure metadata initialization with default values when null during search results.
