Subject: refactor: retire unreferenced modules to an archive directory

A reachability sweep from init.el found eight .el files that nothing in the config loads or references. I moved them under archive/ (off the load-path, still tracked in git) so they stay readable and restorable rather than deleted. archive/README.org records the rule (every .el outside archive/ should be actively used) and why each file was retired.

I retired show-kill-ring, duet-config, and mu4e-org-contacts-setup from modules/, and eplot, profile-dotemacs, titlecase, titlecase-data, and edit-indirect from custom/. Retiring show-kill-ring also removed the orphaned M-K -> M-S-k translation in keyboard-compat, which had left M-K a dead key. Its tests now assert seventeen translations and guard M-K's absence.

+;;; test-show-kill-ring--insert-item.el --- Tests for show-kill-insert-item -*- lexical-binding: t -*-
+
+;;; Commentary:
+;; Tests for `show-kill-insert-item' in show-kill-ring.el — inserts a
+;; kill-ring entry into the current buffer, truncating to
+;; `show-kill-max-item-size' with an ellipsis when too long.  The ellipsis
+;; sits inline for short items and on its own line for items wider than the
+;; frame.  Frame width is read at runtime so the test is environment-stable.
