umi-memory 0.1.0

//! Integration Tests for Memory
//!
//! End-to-end workflow validation for production readiness.
//!
//! These tests validate key Memory workflows:
//! - Semantic search with embeddings
//! - Full remember -> recall -> evolution workflow
//! - Multiple entity extraction
//! - Configuration effects
