 /**
  * bump-version.js — 构建时自动递增 package.json 版本号
+ *
+ * 逻辑：
+ *   检查自上次构建以来的 git commit，若仅包含工程化变更（chore/build/ci/auto bump）或没有新 commit，
+ *   则跳过版本号递增，保持当前版本号。
+ *   否则按指定类型（默认 patch）递增版本号。

  * 用法: node scripts/bump-version.js [patch|minor|major]
- *       默认 patch，每次 npm run build 前自动执行 +0.0.1
