# System tooling. Aligned with Anthropic's official Claude Code devcontainer
# (less/git/procps/sudo/fzf/zsh/man-db/unzip/gnupg2/gh/iptables/ipset/iproute2/
# dnsutils/aggregate/jq/nano/vim) plus extras useful in Claude Code workflows
# (ripgrep, bat, fd-find, tree, wget, curl, ca-certificates, python3+pip).
# Note: Claude Code ships its own bundled ripgrep; the system copy is kept for
# general shell use and as a fallback (USE_BUILTIN_RIPGREP=0).
