docs(load-graph): classify text/editing command modules

Second classification batch: the nine custom-* text/editing command helpers (case, comments, datetime, buffer-file, line-paragraph, misc, ordering, text-enclose, whitespace). I annotated each with the load-graph header contract and added a Batch 2 table to the inventory. They're all Layer 2, eager only to register a C-; submap at load, with no necessary eager reason, so all are Phase 3/4 deferral candidates.

The inventory records a second hidden dependency for Phase 2: custom-buffer-file guards its C-; b registration with (when (boundp 'cj/custom-keymap) ...) and declares the keymap only via eval-when-compile, so the binding silently drops when the module loads without keybindings.

 ;;; Commentary:
+;;
+;; Layer: 2 (Core UX).
+;; Category: L/C.
+;; Load shape: eager.
+;; Eager reason: registers its C-; b buffer/file submap at load. Currently eager
+;;   by init order; a deferral candidate for Phase 3/4.
+;; Top-level side effects: defines cj/copy-buffer-content-map and
+;;   cj/buffer-and-file-map; conditionally registers the latter under C-; b.
+;; Runtime requires: external-open, mm-decode, system-lib. keybindings is needed
+;;   for the C-; b registration but is declared only via eval-when-compile and
+;;   guarded by `boundp', so the binding silently drops standalone. Phase 2 fix.
+;; Direct test load: conditional (C-; b registration skipped without keybindings).
+;;
 ;; This module provides custom buffer and file operations including PostScript
 ;; printing capabilities.
