Add most-used dev tools, sshd/firewall, bash+liquidprompt shell

modules/home/dev-tools.nix provisions the developer's evidenced most-
used CLI/client tooling (gh, tmux, htop, yq-go, tree-sitter, docker,
docker-compose, kubectl, awscli2). modules/home/shell.nix drops zsh/
starship/direnv in favor of bash + liquidprompt, both left entirely to
the user's own dotfiles for config since home-manager can't own
~/.bashrc without conflicting with it. modules/nixos/common.nix adds
sshd (key-only auth) and a firewall baseline for future NixOS hosts.
