Quality improvements: Remove dead code, add unit tests, fix ignored errors
HIGH PRIORITY FIXES: 1. Remove unused progressCallback mechanism (dead code cleanup) 2. Add unit tests for restore package (formats, safety checks) - Test coverage for archive format detection - Test coverage for safety validation - Added NullLogger for testing 3. Fix ignored errors in backup pipeline - Handle StdoutPipe() errors properly - Log stderr pipe errors - Document CPU detection errors IMPROVEMENTS: - formats_test.go: 8 test functions, all passing - safety_test.go: 6 test functions for validation - logger/null.go: Test helper for unit tests - Proper error handling in streaming compression - Fixed indentation in stderr handling
