feat(nix): added binary nix package

[pamburus]

This pull request adds a binary package bin for Nix which uses pre-built binaries from releases.

Benefits

The binary package offers:

• Faster installation - No compilation required
• Reduced dependencies - No need for Rust toolchain
• Consistent builds - Uses the same binaries as GitHub releases

Usage

Run directly:

nix run github:pamburus/hl#bin

Add to profile:

nix profile add github:pamburus/hl#bin

Add to NixOS system configuration:

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-25.05";
    hl.url = "github:pamburus/hl";
  };
  outputs = {nixpkgs, hl, ...}:
  let
    system = "x86_64-linux";
  in
  {
    # this is just an example!
    nixosConfigurations.yourHost = nixpkgs.lib.nixosSystem {
      inherit system;
      modules = [
        ({...}: {
          environment.systemPackages = [
            hl.packages.${system}.bin
          ];
        })
      ];
    };
  };
}
