refactor(nix): dedupe home-manager wiring across hosts ♻️

Browse source 
Extract the per-host home-manager block (useGlobalPkgs, useUserPackages,
backupFileExtension, users.<name> with username/homeDirectory/optional
stateVersion/optional imports) into nixos/lib/home-manager-user.nix.
Each flake-module now imports it with its per-host parameters, removing
~40 lines of boilerplate across the four hosts.

# Shared home-manager wiring for NixOS and nix-darwin hosts.
#
# Usage (from a flake-module):
# modules = [
# inputs.home-manager.nixosModules.home-manager # or .darwinModules
# (import ../lib/home-manager-user.nix {
# lib = inputs.nixpkgs.lib;
# user = "danny";
# homeDirectory = "/home/danny";
# stateVersion = "25.11"; # optional
# userImports = [ ../home/danny/home.nix ]; # optional
# })
# ];
{ lib
, user
, homeDirectory
, stateVersion ? null
, userImports ? [ ]
}:
{
home-manager.useGlobalPkgs = true;
home-manager.useUserPackages = true;
# Automatically back up files before home-manager overwrites them.
home-manager.backupFileExtension = "backup";
home-manager.users.${user} = { ... }: {
imports = userImports;
home = {
username = user;
# Force an absolute path even if another module sets a bad value.
homeDirectory = lib.mkForce homeDirectory;
} // lib.optionalAttrs (stateVersion != null) {
stateVersion = stateVersion;
};
};
