Add server CLI tools installer for Ubuntu/Debian servers

Introduce a self-contained repo with an interactive install.sh that
provisions zsh, oh-my-zsh, aliases, bat/yazi configs, docker shortcuts,
and git-delta pager setup. Configs are adapted from dotfiles for SSH-only
servers — no desktop or neovim dependencies.

Installer supports --all, --update (git pull + re-run), and --uninstall
with backup restore. Core packages include vim (default editor), yazi via
apt, and idempotent apt installs with warnings for eza and git-delta when
repos lack them.
