Subject: zsh: add hm wrapper for flake-based home-manager

The standalone 'home-manager' command defaults to the legacy
~/.config/home-manager/home.nix and errors out for flake users. The
wrapper auto-selects the host/vm profile by /etc/os-release ID and
points at whichever dotfiles checkout exists on the machine.

Usage:
    hm news
    hm switch
    hm generations
