docs(load-graph): classify remaining domain and optional modules

Final classification batch: the last 19 modules — linear-config, local-repository, lorem-optimum, mail-config, markdown-config, music-config, pdf-config, quick-video-capture, reconcile-open-repos, restclient-config, slack-config, system-commands, telega-config, tramp-config, transcription-config, video-audio-recording, vterm-config, weather-config, wrap-up. I annotated each header, added a Batch 9 table to the inventory, and extended the validation allowlist. 101 of 102 modules are now classified; only elfeed-config remains, deferred on its test fix.

Two more hidden dependencies turned up. video-audio-recording uses the boundp shim for its C-; r binding, and mail-config registers C-; e directly without requiring keybindings, so it errors standalone rather than degrading. Both recorded for Phase 2.

 ;;; Commentary:
 ;;
+;; Layer: 3 (Domain Workflow).
+;; Category: D/S.
+;; Load shape: eager.
+;; Eager reason: registers the C-; ! system-command keymap; high-impact commands
+;;   that should run only by command (command-loaded target).
+;; Top-level side effects: defines a system-command keymap under cj/custom-keymap.
+;; Runtime requires: keybindings, rx.
+;; Direct test load: yes (requires keybindings explicitly).
+;;
 ;; System commands for logout, lock, suspend, shutdown, reboot, and Emacs
 ;; exit/restart. Provides both a keymap (C-; !) and a completing-read menu.
