/**
 * Update content feature module.
 *
 * Purpose: Handle document changes and annotation context updates.
 * Orchestrates adapters and core to detect and process annotation changes.
 *
 * Key responsibilities:
 * - Detect document changes during transactions
 * - Compare current state with original annotations
 * - Detect content, occurrence, and container changes
 * - Update Velt contexts for changed annotations
 * - Update marks in editor if needed
 *
 * Dependencies:
 * - adapters/host/doc.ts (for change detection)
 * - adapters/velt.ts (for context updates)
 * - adapters/host/marks.ts (for mark updates)
 * - core/state.ts (for state access)
 * - utils/console.ts (for logging)
 *
 * IMPORTANT: This module MUST NOT import editor or Velt types directly.
 * All SDK access goes through adapters.
