feat: add verb and noun metadata handling in storage adapters

Browse source 
- Implement saveVerbMetadata and getVerbMetadata methods for managing verb metadata.
- Implement saveNounMetadata and getNounMetadata methods for managing noun metadata.
- Update storage adapters to use HNSWVerb instead of GraphVerb for improved performance.
- Deprecate methods that require loading metadata for edges, returning empty arrays instead.
