/**
 * review-report-checker 封印框升级补丁 v2 (2026-04-25)
 *
 * 迁移: v1 章节封印 → v2 封印框 (方案 A)
 *
 * 语义变化:
 *   - "章节封印" → "封印框"
 *   - 模板 M: BOOKWORM REVIEW SEAL (╱╲ 风) → BOOKWORM · CODE REVIEW (╔╗ 风)
 *   - 模板 L: SAFETY SEAL → CODE REVIEW · SAFETY 分节
 *   - 模板 XL: SEMANTIC DIFF 追加节 (锚定句保留在交付条幅)
 *
 * 幂等: sentinel "sealed-frame:v2" 注入, 已打过则跳过
 * 兼容: 支持从 v1 (章节封印) 平滑迁移, 也支持原始未升级文件
 * 原子: tmp + rename
 * 备份: scripts/patches/bak/review-report-checker.js.sf.<ts>.bak
