**feat(core, storage, tests): enhance verb construction with timestamps and metadata**

- **Core**: Improved verb creation logic by adding `createdAt`, `updatedAt`, and `createdBy` attributes. These fields include timestamped metadata (`seconds`, `nanoseconds`) and source augmentation/service information for better tracking.
- **Storage**: Refactored `BaseStorage` methods to utilize internal variants (e.g., `saveVerb_internal`, `getNoun_internal`). Added support for new verb attributes while maintaining backward compatibility with existing data structures.
- **Tests**:
  - Updated `s3-storage.test.ts` and `opfs-storage.test.ts` to validate changes in verb attributes such as timestamps and augmentation metadata.
  - Added assertions for `createdAt`, `updatedAt`, and `createdBy` fields in test cases.
- **Cleanup**: Replaced ambiguous type aliases like `Edge` and `HNSWNode` with clearer equivalents (`Verb` and `HNSWNoun_internal`) for consistency across storage adapters.

**Purpose**: Enhance metadata tracking and standardize attribute handling across storage and core modules to ensure accurate and consistent data throughout the system.
