/**
* Cache and System Validation Real Tests
*
* Real tests for cache creation, population, persistence, and integrity validation.
* These tests validate the critical .folder-mcp cache system that enables fast indexing and search.
*
* ⚠️ CRITICAL: These tests use REAL files, REAL services, NO MOCKS
*
* Test Categories:
* 1. Cache Creation and Population
* 2. Cache Contents Validation
* 3. Cache Persistence and Restart Recovery
* 4. Cache Invalidation and Updates
* 5. Index Integrity and Search Performance
* 6. Embedding Storage and Retrieval
* 7. Metadata Caching and Consistency
* 8. System Performance and Concurrent Access
