fix(keys): destructive delete on capital D, diff on lowercase d

C-; b d now runs cj/diff-buffer-with-file (the op I hit most, comparing a buffer against the saved file) and C-; b D runs cj/delete-buffer-and-file. The destructive command sat on the easy lowercase key and diff on the capital. A keymap-lookup test guards the swap.

+;;; Commentary:
+;; `cj/buffer-and-file-map' should put the destructive op on the capital key and
+;; the frequently-used op on the easy lowercase key: D = delete-buffer-and-file,
+;; d = diff-buffer-with-file.  Guards the swap against silently reverting.
+
+;;; Code:

+(require 'ert)

+(add-to-list 'load-path (expand-file-name "modules" user-emacs-directory))
+
+;; Stub dependencies before loading the module (mirrors the sibling tests).
