Crate khive_storage 

Storage capability traits — contracts that backend implementations satisfy.

This crate contains zero implementations. It defines:

• SqlAccess: base SQL capability (reader / writer / transaction)
• VectorStore: embedding storage and similarity search
• TextSearch: full-text search and document indexing
• GraphStore: directed edge CRUD and graph traversal
• NoteStore: temporal-referential note CRUD
• EventStore: append-only operation log
• Shared types (SqlValue, VectorSearchHit, TextSearchHit, etc.)
• StorageError: unified error type
