Updated the Meson post-install script to import shutil and add a helper that checks tool availability before invoking post-install commands. This prevents hard failures when optional desktop tooling is not installed (e.g., on macOS/Homebrew CI).

Replaced direct subprocess.call(...) calls for gtk-update-icon-cache and update-desktop-database with guarded calls that emit a clear “Skipping …: command not found” message when absent, while preserving existing behavior when present.
