Another dup error, this time homeManager.

I tried to add a simple, static aspect as includes in den.aspects.alice.includes, these are the changes:

diff --git a/templates/default/modules/aspects/alice.nix b/templates/default/modules/aspects/alice.nix

     # den included batteries that provide common configs.
     includes =
       let
         # deadnix: skip # demo: enable <> on lexical scope
         inherit (den.lib) __findFile;
+
+        enableEmacs.homeManager = { pkgs, ... }: {
+          programs.emacs.enable = true;
+          programs.emacs.package = pkgs.emacs30;
+        };
       in
       [

         <den/primary-user> # alice is admin always.
         (<den/user-shell> "fish") # default user shell
       ];

and here's the error:

       Use `lib.mkForce value` or `lib.mkDefault value` to change the priority on any of these definitions.

PR #88 Fixed one issue, the home-manager integration was registering with a context { host, ...} which evidently fired multiple times, so it was changed to takes.exactly({ OS, host }: ... }) to emit once per host.

However, ccording to #88 (comment) another duplication happens when sharing a single aspect between an standalone-hm and an os-managed-hm. I need to fix that because I'd like to have shared aspects between them.
