It stopped a real install. The guard covered the wrong half: a PPA that fails to
ADD is caught and skipped, but one that adds cleanly while carrying no package for
the running codename gets past that and dies on `pkg_install_now fastfetch`.
It was also the only tool in the set with no source but a third-party PPA on Ubuntu
24.04 and older. A neofetch clone is not worth a branch in a script whose whole job
is to survive machines nobody has seen.
Removed from tools_default, the tool_command mapping and its installer. No shell
config invoked it, so nothing is left calling a missing binary.
software-properties-common stays in the core apt list for now, with a note: it
provides add-apt-repository, the fastfetch PPA was its only caller, and Docker
writes its own sources.list.d entry by hand — so it is now dead weight. Left as a
separate decision rather than folded into this one.
Verified: bash -n on all four scripts, and no live reference remains.
