High-performance buffer system for editing massive files with intelligent memory management and undo/redo capabilities

/**
 * @fileoverview Enhanced Paged Buffer System with Line Tracking and Named Marks
 * @description High-performance buffer system for handling arbitrarily large files
 * with constant memory usage, intelligent undo/redo, robust address translation,
 * comprehensive line tracking, named marks support, and pluggable storage backends.
 *
 * @example
 * import { PagedBuffer } from 'paged-buffer-system';
 *
 * const buffer = new PagedBuffer();
 * buffer.enableUndo();
 * await buffer.loadFile('large-file.txt');
 *
 * // Basic operations
 * await buffer.insertBytes(100, Buffer.from('Hello'));
 *
 * // Line operations
 * const lineCount = await buffer.getLineCount();
 * const lineInfo = await buffer.getLineInfo(5); // Get info about line 5
 *
 * // Named marks
 * buffer.setMark('bookmark1', 100);
 * const bookmarkPos = buffer.getMark('bookmark1');
 * const allMarks = buffer.getAllMarks();
 *
 * // Enhanced operations with marks
 * const result = await buffer.getBytes(0, 100, true); // Include marks
 * await buffer.insertBytes(50, Buffer.from('text'), [
 *   { name: 'mark1', relativeOffset: 0 },
 *   { name: 'mark2', relativeOffset: 4 }
 * ]);
