docs(load-graph): classify dev, diff, help, lint, and VC modules

Fifth classification batch: the development-workflow entry points and package config — coverage-core, coverage-elisp, dev-fkeys, diff-config, help-config, help-utils, flycheck-config, test-runner, vc-config. I annotated each header, added a Batch 5 table to the inventory, and extended the validation allowlist. 42 of 102 modules are now classified.

Two more hidden dependencies turned up, both about cj/custom-keymap. dev-fkeys repeats the custom-buffer-file boundp shim for its C-; P binding. flycheck-config binds (:map cj/custom-keymap ...) through use-package without requiring keybindings, so it fails to load standalone. Both recorded for the Phase 2 dependency pass.

 ;;; Commentary:
-
+;;
+;; Layer: 2 (Core UX).
+;; Category: C/P.
+;; Load shape: eager.
+;; Eager reason: Ediff and diff UX defaults; eager only by init order, a
+;;   package-load deferral candidate.
+;; Top-level side effects: package configuration via use-package.
+;; Runtime requires: none.
+;; Direct test load: yes.
+;;
 ;; I've configured Ediff for a clean and efficient diff experience.
 
 ;; • Ediff will use a plain control window, horizontal splits, ignore whitespace, and only highlight the current change.
