Subject: [PATCH 1/3] feat(nix): enhance unfree package configuration in
 home-manager and NixOS

- Updated the Nix configuration to allow unfree packages by setting `nixpkgs.config.allowUnfree = true;`.
- Expanded the `allowUnfreePredicate` to include "crush" alongside existing packages "claude-code" and "qwen-code" for improved package management.
