**feat(storage): add pagination and filtering support for nouns and verbs**

Browse source 
- Introduced `PaginationOptions`, `NounFilterOptions`, and `VerbFilterOptions` types for improved query flexibility in data retrieval operations.
- Added `getNouns` and `getVerbs` methods with pagination and filtering capabilities, replacing existing methods for broader use cases and scalability.
- Marked legacy methods (`getAllNouns`, `getAllVerbs`, `getVerbsBySource`, `getVerbsByTarget`, `getVerbsByType`) as deprecated, directing users to use new methods.
- Updated `coreTypes`, `memoryStorage`, and related modules to support new functionality, including cursor and offset-based pagination handling.
- Updated fallback logic for storage adapters, ensuring compatibility with non-paginated operations when required.

**Purpose**: Enhance scalability and query precision by implementing paginated and filtered retrieval of nouns and verbs, aligning query methods with modern requirements.

### Added
### Changed
- Unified getNouns and getVerbs methods to improve code consistency
- Removed deprecated warnings from getAllNouns, getAllVerbs, getVerbsBySource, getVerbsByTarget, and getVerbsByType
- Implemented getAllNouns and getAllVerbs to use the paginated versions internally
- Improved method documentation with clearer parameter and return type descriptions
### Fixed
