Module storage 

Storage layer abstraction.

This module provides a three-layer storage architecture:

• Persistence: Authoritative storage (SQLite, PostgreSQL, Filesystem)
• Index: Full-text search (SQLite + FTS5, PostgreSQL, RediSearch)
• Vector: Embedding similarity search (usearch, pgvector, Redis)
