Real-world trigger: libQt6PrintSupport.so.6 missing from CheatEngine portable binary on Linux Mint 22.3. Windows/macOS migrants double-click a binary, nothing happens, and they have no idea why — the dynamic linker error goes to journald silently. Robin catches 'cannot open shared object file: No such file or directory' in journald and explains the Linux shared library model, pointing to the right package manager command (apt/pacman/dnf/zypper) per distro family. Also documents why 'pip install pyqt6' doesn't fix system library errors. Added to 23 pattern files covering all source OS / target distro family combinations.
