**feat(core, statistics, storage): enhance service-level statistics tracking and result filtering**

Browse source 
- **Core**: Introduced a `getCurrentAugmentation` method for detecting active augmentation names. Updated metadata handling to include `createdBy`, `createdAt`, and `updatedAt` attributes for improved tracking.
- **Storage**: Added support for service-based statistics tracking with new methods such as `incrementStatistic`, `decrementStatistic`, and `updateHnswIndexSize`. Implemented persistence for statistics in storage adapters.
- **Statistics**: Enhanced `getStatistics` functionality to provide service-specific breakdowns and support filtering by services. Improved noun, verb, and metadata tracking mechanisms.
- **Search**: Added `service` option to filter results during searches for nouns, verbs, and metadata, ensuring accurate service-based query results.
- **Refactor**: Simplified search logic by integrating HNSW index filtering for better performance when retrieving service-specific results.
- **Tests**: Added comprehensive test coverage for service-level statistics and filtering by service.

**Purpose**: Improve service-level data tracking and analytics while enhancing functionality for filtering and maintaining metadata accuracy to support detailed insights for diverse use cases.
