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.
