feat(patterns): add missing-shared-library pattern to all distro families

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.
