- Added `ErrorRecovery.cc` and `ErrorRecovery.h` for retry and circuit breaker implementations.
- Enhanced swap file handling with transient error retries and exponential backoff (e.g., ENOSPC, EDQUOT).
- Integrated circuit breaker into SwapManager to gracefully handle repeated failures, prevent system overload, and enable automatic recovery.
- Updated `DEVELOPER_GUIDE.md` with comprehensive documentation on error recovery patterns and graceful degradation strategies.
- Refined fsync, temp file creation, and swap file logic with retry-on-failure mechanisms for improved resilience.
