refactor: split custom-misc.el into focused modules

custom-misc.el was an incoherent grab-bag, so anything small defaulted to landing there. I split its eight commands by concern. Three moved into new modules: custom-format (region/buffer reformat), custom-counts (word and character counts), and custom-text-transform (fraction glyphs). The other three went to existing homes: the previous-buffer toggle to custom-buffer-file, the delimiter jump to custom-line-paragraph, and the align-regexp space advice with its alignment and fill bindings to custom-whitespace.

The C-; bindings, which-key labels, and the six test files moved with their functions, and custom-misc.el is deleted. No behavior change: every command keeps its name and its C-; key.

+;;; custom-counts.el --- Word and character counts -*- coding: utf-8; lexical-binding: t; -*-
+
+;;; Commentary:
+;;
+;; Layer: 2 (Core UX).
+;; Category: L.
+;; Load shape: eager.
+;; Eager reason: registers its C-; # w and C-; # c command bindings at load.
+;; Top-level side effects: binds the count commands under C-; # w and C-; # c.
+;; Runtime requires: keybindings.
+;; Direct test load: yes (requires keybindings explicitly).
+;;
+;; Count words or characters in the active region, or the whole buffer when no
+;; region is active, and report the total in the minibuffer.  Split out of the
+;; former custom-misc.el grab-bag.
