add CI workflow for nix flake check#5
Merged

Conversation
Runs `nix flake check` on ubuntu-latest for every push to main and every pull request. Uses DeterminateSystems' nix-installer plus magic-nix-cache so incremental reruns don't rebuild every gem from source. x86_64-linux only for now; darwin/aarch64 coverage can be layered on later without changing this workflow's shape.
