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.

+;; Load shape: eager.
+;; Eager reason: the F4/F6 developer command entry points.
+;; Top-level side effects: six global F-key bindings; conditionally registers a
+;;   C-; P binding.
+;; Runtime requires: cl-lib, system-lib. keybindings is needed for the C-; P
+;;   binding but is declared only via eval-when-compile and guarded by `boundp',
+;;   so that binding silently drops standalone. Phase 2 fix.
+;; Direct test load: conditional (C-; P registration skipped without keybindings).
