Subject: [PATCH] fix(src/brainyData): enforce consistent formatting and
 improve fallback mechanisms

- Applied consistent formatting improvements, including line breaks, parentheses usage, and object destructuring, to enhance code readability and maintainability.
- Enhanced the fallback mechanism during Universal Sentence Encoder initialization by implementing a retry approach with error handling.
- Refactored `addBatch` processing for both vector and text items to improve clarity and adhere to project coding standards.
- Optimized initialization safeguards with structured retry implementations, ensuring robust error resiliency.

These changes align the codebase with established formatting guidelines and improve the reliability of embedding initialization processes.
