- flake.nix: new entrypoint using nixpkgs-unstable + home-manager input;
builds as nixosConfigurations.chexit (nixos-rebuild switch --flake .#chexit)
- home.nix: Home Manager config for user chexit with zsh (p10k theme,
autosuggestion, syntax highlighting, completion)
- shell.nix: stripped to system-level programs.zsh.enable only;
user-specific zsh config moved to home.nix
