/**
 * Slash command, context menu, and autocomplete dispatcher.
 *
 * Submodules own command handlers by topic:
 *   helpers.js     — requireStaffRole, fetchLoggingChannel
 *   escalation.js  — runEscalation, runDeescalation, handleEscalate, handleDeescalate
 *   close.js       — handleForceClose, handleCancelClose, handleCloseTimer (+ finalize/transcript)
 *   response.js    — /response subcommands + handleAutocomplete
 *   panel.js       — handlePanel, handleSignature
 *   contextMenu.js — handleCreateTicketFromMessage, handleViewUserTickets
 *
 * This file holds the dispatchers, the small "remainder" handlers
 * (channel-mod, settings toggles, /help, /notifydm), and the public
 * module.exports surface that handlers/buttons.js + broccolini-discord.js
 * import from `require('./commands')`.
