Collaborative editing solution for Lexical based on Loro CRDT

import { type LexicalEditor } from 'lexical';
/**
 * DiffMerge System for Lexical Editor
 *
 * This module provides sophisticated differential updates for Lexical editor states,
 * preventing wholesale state replacement that would destroy React decorator nodes
 * like YouTube embeds, counters, and other custom components.
 *
 * Key Features:
 * - Selective node updates (only changed content)
 * - Decorator node preservation (YouTube, Counter nodes remain untouched)
 * - Table structure support with cell-level updates
 * - Graceful fallback for unsupported operations
 * - Deep content comparison to minimize unnecessary updates
 *
 * Usage:
 * ```typescript
 * const success = applyDifferentialUpdate(editor, newState, 'collaboration');
 * if (!success) {
 *   // Fall back to setEditorState if differential update fails
 *   editor.setEditorState(newState);
 * }
 * ```
