Complete Linux system optimization suite with tmpfs, zram, and German locale support
- Fixed missing setup_tmpfs() function that was causing silent failures - Added comprehensive system scanning for browsers, IDEs, gaming caches - Implemented detailed optimization information display for transparency - Added German locale compatibility for 'free' command (Speicher: vs Mem:) - Fixed division by zero errors in RAM calculations - Created tmpfs-info.sh helper script for detailed status reporting - Enhanced scanning to work on already-optimized systems - Added comprehensive optimization breakdowns with purpose explanations
