Subject: feat(nix): hybrid setup with flakes + direnv for per-project dev
 shells
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Install Nix (multi-user daemon) on Arch and wire up direnv so any project
can declare its toolchain in a flake.nix and get a hermetic dev shell on
cd. No NixOS, no home-manager, no migration off paru/chezmoi — just one
new package manager scoped to project dev shells.

- meta/nix.txt: nix from extra repo
- meta/dev.txt: direnv (general-purpose, not nix-specific)
- systemd-units/system/nix.txt: nix-daemon.socket (socket-activated)
- etc/nix/nix.conf: enable flakes + nix-command, trusted-users=@wheel,
  auto-optimise-store, keep-outputs/derivations so direnv envs survive GC
- dot_config/direnv/direnvrc: load nix-direnv 3.1.1 via source_url with
  pinned sha256 (not packaged for Arch; refusing -git AUR)
- dot_config/nix/templates/{flake.nix,dev/}: flake template usable via
  'nix flake init -t ~/.config/nix/templates'
- dot_config/zsh/dot_zshrc: 'eval "$(direnv hook zsh)"'
