- build-essential (~150MB with gcc/g++) was installed for every project; it is only needed when a project compiles C. Moved into the 'rust' toolchain arm (cargo links C deps when installing crates). - nodejs 22 was installed unconditionally via the nodesource repo; moved to the 'node' toolchain arm so non-node projects skip it. - Kept all interactive/network/firewall tooling (vim, tmux, zsh, fzf, gh, jq, ripgrep, iptables, socat, ...) — they're small and aidc relies on several (socat for the clipboard bridge, iptables for the firewall). Expected saving: ~200-300MB per non-node, non-C project image. Refs cyfinoid#11

Summary
Two heavy apt packages were installed unconditionally in every aidc image, even for projects that never use them:
build-essential(~150 MB with gcc/g++/make) — only needed when a project compiles C code.nodejs22 (~70 MB + nodesource repo setup) — only needed when the project has a Node toolchain.Changes (
