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
