 * Awards XP to users for sending messages in text channels.
 *
 * This handler implements the core XP awarding mechanics:
 * - Random 15-25 base XP per message
 * - Cooldown enforcement (per-user)
 * - Channel and role exclusions (No-XP lists)
 * - Multiplier resolution (server × max(role) × user)
 * - Level change detection and event emission
 *
 * Early exits for:
 * - Bot messages
 * - DMs (no guild context)
 * - Non-text channels
 * - No-XP channels
 * - No-XP roles
 * - Within cooldown period
