- Updated .gitignore to include all .exe files and ensure .smashignore is tracked.
- Expanded README.md with advanced configuration options for garbage collection algorithms, detailing available algorithms and use cases.
- Modified launch.json to include memory and disk garbage collection flags for better configuration.
- Refactored root.go to introduce memoryGC and diskGC flags for garbage collection algorithms.
- Implemented hash extraction and verification in steamcache.go to ensure data integrity during caching.
- Added new tests in steamcache_test.go for hash extraction and verification, ensuring correctness of caching behavior.
- Enhanced garbage collection strategies in gc.go, introducing LFU, FIFO, Largest, Smallest, and Hybrid algorithms with corresponding metrics.
- Updated caching logic to conditionally cache responses based on hash verification results.
- Added Prometheus client library for metrics collection.
- Refactored garbage collection strategy from random deletion to LRU (Least Recently Used) deletion.
- Introduced per-key locking in cache to prevent race conditions.
- Enhanced logging with structured log messages for cache hits and misses.
- Implemented a retry mechanism for upstream requests with exponential backoff.
- Updated Go modules and indirect dependencies for better compatibility and performance.
- Removed unused sync filesystem implementation.
- Added version initialization to ensure a default version string.
