- Remove unused overlay filesystem configuration and references - Remove overlayfs sections from all profile JSON files - Remove OVERLAY_ENABLED/OVERLAY_PROTECT_CONFIGS from config - Update documentation to focus on tmpfs optimization - Add overlay detection and removal functionality for cleanup - Add remove_overlays() function with safe unmounting - Add overlay status reporting in final optimization summary - Add test-overlay-detection.sh for testing detection logic - Simplify codebase by removing complex unused features - Focus on proven desktop optimizations (tmpfs, zram, kernel)
