perf: optimize system cleanup by merging find operations
Performance improvements: - Merge 3 separate find operations into 1 for /Library/Caches - Combine *.cache, *.tmp, *.log patterns in single scan - Reduces filesystem traversal overhead - Merge 2 find operations into 1 for /private/var/log - Combine *.log and *.gz patterns - Optimize diagnostics cleanup with single combined scan - Merge Special, Persist, and tracev3 patterns - Reduces redundant directory traversal - Use find -delete for batch removal of memory exception reports - More efficient than iterative removal for large file counts - Add summary logging to operations.log UI improvements: - Add granular spinner messages for each cleanup stage - Separate diagnostic logs and power logs output for clarity - Add progress feedback during Time Machine status check Tests: - Update sudo mock functions to support new combined find patterns - Verify find -delete usage for memory exception cleanup - Update assertions to match optimized implementation
