Subject: [PATCH] fix(ci): migrate from nix-installer-action +
 flake-checker-action to determinate-nix-action@v3

Removes DeterminateSystems/flake-checker-action which runs on Node.js 20,
deprecated on GitHub Actions June 2, 2026. determinate-nix-action@v3 is the
consolidated replacement that bundles both Nix installation and flake checking.
