Andrew Phillips a3eb9e7056 fix: address critical memory safety, error handling, concurrency and security issues ...

This commit fixes several critical issues across the codebase:
1. Memory safety & resource leaks: Added proper cleanup for compression engine processes using RAII patterns
2. Error handling: Replaced unsafe unwrap() calls with proper error propagation using ok_or_else()?
3. Concurrency issues: Improved diff mode thread safety with proper error handling and RAII guards
4. Security concerns: Added validation for item IDs to prevent path traversal vulnerabilities
5. Database design: Wrapped database operations in transactions for atomicity in save/update modes
