feat(auto-dim): dim non-selected windows via auto-dim-other-buffers

I added auto-dim-config, a module that loads my local auto-dim-other-buffers fork and dims windows that don't have focus so the selected window stands out. A non-selected window drops to a pure-black background with faded gray text. The dimmed faces live in the dupre theme (themes/dupre-faces.el) so they track theme switches, and the module remaps default, the font-lock faces, and org-block onto them so syntax-highlighted code fades too rather than staying lit. Fringe is left out because dimming it forces a full-frame refresh that flickers on this non-pgtk build.

dim-on-focus-out is nil, so tabbing to a browser or terminal on Hyprland doesn't dim the whole frame. vterm and agent windows don't dim either, because the terminal paints its own per-cell colors past the face remap. I'm keeping that, since the agent's output stays readable while I work in code on the other side.

The module loads after the theme, carries a load-graph header, joins the header-contract allowlist, and the inventory moves to 103 of 103 classified.

+;;; Commentary:
+;; auto-dim-config configures the local auto-dim-other-buffers fork: dim only
+;; non-selected windows within Emacs (not the whole frame on focus-out), drop
+;; fringe from the dimmed faces to avoid flicker on this non-pgtk build, and
+;; enable the global mode.  Guarded with `skip-unless' because the fork lives
+;; in ~/code and may be absent on a clean checkout.
