/**
 * review-report-checker 章节封印升级补丁 (2026-04-25)
 *
 * 目标: hooks/review-report-checker.js 的 required[] 提示词升级为方案 E
 *   - 裁决行改为 "裁决 │ PASS / BLOCKED (宪章 §2.1 · 章节封印)"
 *   - 各维度提示追加模板引用 (模板 M/L/XL)
 *   - header 追加 "采用章节封印模板" 文案
 *
 * 不改变: SOURCE_EXTENSIONS / 行数阈值 / 敏感路径判定 / logCompliance 契约
 *
 * 幂等: sentinel "chaptered-seal:v1" 注入文件顶部, 已打过则跳过
 * 原子: tmp + rename
 * 备份: scripts/patches/bak/review-report-checker.js.cs.<ts>.bak
