In common-nixos.nix (every NixOS host): - programs.nix-ld for all hosts, not just WSL — foreign dynamic binaries (VS Code server, prebuilt toolchains) run on the dev boxes too. Removed the now-redundant per-host enable from the EDaaS config. - nix-community.cachix.org substituter (merges with the Asahi cache). - Noto sans + colour-emoji fonts and fontconfig defaultFonts mapping, so the WSL box (and anything asking fontconfig for "monospace") stops rendering tofu.
