shodh-memory 0.2.0

//! Tests for FileMemoryStore - Codebase Integration (MEM-36)
//!
//! Tests cover:
//! - CRUD operations for FileMemory
//! - Codebase scanning with limits
//! - File indexing and key item extraction
//! - File type detection
//! - Heat score calculation
//!
//! Run with: cargo test --test file_memory_tests -- --nocapture
