Subject: [PATCH] fix(nix): switch nixpkgs input from nixos-24.11 to
 nixos-unstable (#5520)

* fix(nix): switch nixpkgs input from nixos-24.11 to nixos-unstable

nixos-24.11 reached EOL on 2025-06-30. For a dev tool, tracking a
frozen release branch causes dependency versions to go stale.
nixos-unstable provides rolling updates and is the conventional
choice for development packages.

* docs(website): update nix flake example
