//! 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
